Question

(6,3) graph of f(x) find the point of for the function f(-1/2x).

Answer 1

(-12,3)

Explanation:

Since (6,3) is on the graph of f(x), then f(6)=3.

We want to see if we can use f(6)=3 to find a point on the graph of f(-1/2x).

If you compare -1/2x to 6, what must x be so they have the same value? x=-12.

If that wasn't obvious to you, just solve:

-1/2x=6

Multiply both sides by -2:

x=-12

So if we replace x with -12 in f(-1/2x) we get

f(-1/2*-12)

f(6)=3

And we were given this f(6)=3 so f(-1/2*-12)=3.
