Suppose that the functions q and r are defined as follows q(x)=-2x+1 r(x)=-5x-4 Find the following (qºr)(1) (rºq)(1) ...

I am having trouble doing this question. Can someone please explain the steps. Thank you!

I've heard that the amount of snowfall is a function of date. This makes sense to me as there is only one specific date, so therefore the date does not produce two different outputs. But if you...

f(x) = (3x) / (x2 + 1). Show that f-1(x) = (6 - 3x2) / (x2 + 2)2

Let f and g be functions such that g(x) =2f(x+1)+5 Let h(x) = -g(3x). The point A (6,5) in the graph is mapped to the point A´ on the graph of h. Find A´

For example, if I have y = f(ax) how would I isolate x using these variables? Like if i knew the function(f) was squaring then I would do: √y = ax --> √y / a =x . However, how would I...

A) list the independent and dependent quantities b) find the reasonable domain and range value c) write the reasonable domain and range as inequalities.

y= square root of x+5

A sequence is defined by the recursive function f(n + 1) = –10f(n). If f(1) = 1, what is f(3)?

Let f(x)= x2. Write the equation for the final transformed graph if the following transformations are applied to f: stretch vertically by a factor of 2; shift downward by 5 units; shift right...

The position function of a particle in rectilinear motion is given by s(t) = 2t^3 – 21t^2 + 60t + 3 for t ≥ 0 with t measured in seconds and s(t) measured in feet. Find the position and acceleration...

function: f(x) = x2 + 3 domain: {-3,0,3}

Suppose that the function g is defined, for all real numbers, as follows. g(x)= -4 if x ≠-2 -2 if x =-2 Find...

A taxi ride costs 40 for the first 400 meters and each additional 300 meters adds 3.50 to the fare. Use a piecewise function to represent the taxi fare in terms of the distance in meters...

I'll like to have like a general idea of how it works using notations and dummy letters

k(x) = −x2 − 5x + 6 A.) k(√5) B.) k(a + 5) C.) k(−x) D.) k(x2)

A hotel chain charges $75 each night for the first two nights and $50 for each additional night’s stay. The total cost function T is a function of the number of nights x that a guest stays. Write...
