In analytic geometry , an asymptote ( / ˈ æ s ɪ m p t oʊ t / ) of a curve is a line such that the distance between the curve and the line approaches zero as one ...

If the ordered pair (-5/2, y) lies on the graph of y = 7 - 2x, find the value of y. Wrong: 19/2 Choose the pair of numbers that is not a solution to the given equation. D) {eq}f(x) = 2 \cos (x) + 1{/eq} Graph A diagram showing the relation between variable quantities, typically of two variables, each measured along one of a pair of axes at right angles. Here is the graph: graph{y=(cosx)^2 [-10, 10, -5, 5]} Remember the double-angle formula for cosine: cos(2x) = 2cos^2(x) -1 Add one to both sides: cos (2x) + 1 = 2cos^2(x) Divide both sides by two: 1/2cos(2x) +1/2 = cos^2(x) You now have a standard cosine equation with Amplitude = 1/2 Period = pi Vertical Shift = up by 1/2 every point on the original graph is an ordered pair (x,y) where y = f(x). For the second graph, the y values will be doubled in each case, for the original x values. So this is a VERTICAL STRETCH. D) {eq}f(x) = 2 \cos (x) + 1{/eq} Graph A diagram showing the relation between variable quantities, typically of two variables, each measured along one of a pair of axes at right angles. A Taylor Series is an expansion of some function into an infinite sum of terms, where each term has a larger exponent like x, x 2, x 3, etc. Example: The Taylor Series for e x e x = 1 + x + x 2 2! + x 3 3! + x 4 4! + x 5 5! + ... Find two quadratic functions whose graph have given x-intercepts. Find one function whose graph opens upward and another whose graph opens downward. (-4,0) (0,0) College Algebra. graph linear equation Y=1/2x-3 and -x+2y=-6 . graphing lines in the form. graph linear equation 3x-6y-9=0 . College Math. 1. (a) By graphing the function f(x) = (cos(2x) − cos(x))/x2 and zooming in toward the point where the graph crosses the y-axis, estimate the value of lim x → 0 f(x). (A graphing calculator is recommended.) -3/2 Correct: Your answer is correct. (b) Check your answer in part (a) by evaluating f(x) for values of x that approach 0. Trigonometry. Graph y=cos (2x) y = cos (2x) y = cos ( 2 x) Use the form acos(bx−c)+ d a cos ( b x - c) + d to find the variables used to find the amplitude, period, phase shift, and vertical shift. a = 1 a = 1. b = 2 b = 2. c = 0 c = 0. d = 0 d = 0. Find the amplitude |a| | a |. Get an answer for 'write the function whose graph is the graph of y=(x+3)^2 but is reflected about the x axis.' and find homework help for other Math questions at eNotes The graph of the function is the set of all points $\left(x,y\right)$ in the plane that satisfies the equation $y=f\left(x\right)$. If the function is defined for only a few input values, then the graph of the function is only a few points, where the x -coordinate of each point is an input value and the y -coordinate ... Marcus can choose between a monthly salary of $1,250 plus 5% of sales or$2,400 plus 4% of sales. He expects sales between $5,000 and$10,000 a month. Complete the explanation to show which salary option he should choose based on how much he could make. He should choose the option that pays . With option 1 he would make $____ to$____.

Jan 24, 2017 · Assume your quadratic function has one x input for each y output: (Image 1) First, construct an Excel table with X and Y headers, and straightline values in the X column. 3. Graphs of polynomial functions We have met some of the basic polynomials already. For example, f(x) = 2is a constant function and f(x) = 2x+1 is a linear function. f(x) x 1 2 f(x) = 2 f(x) = 2x + 1 It is important to notice that the graphs of constant functions and linear functions are always straight lines.
