Question

Given that (9,2) is on the graph of f(x), find the corresponding point for the function f(-3/4x)

Answer 1

Answer:

($-\frac{8}{3},2$)

Step-by-step explanation:

Since (9,2) is a point on the graph of f(x), we can say that:

f(9) = 2

Looking at the funtion f(-3/4x), what should the value of x be such that the input of the function becomes 2?

We would solve it by:

$-\frac{3}{4}x=2\\\frac{-3x}{4}=2\\-3x=8\\x=-\frac{8}{3}$

Hence, the new point on the graph is  ($-\frac{8}{3},2$)
