Question

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

Answer 1

The corresponding point on the graph 4f(x) is (-36,16)

The cordinates of the function f(x) is (-9,4) and this cordinates shows a point on the graph. The first cordinates is the x coordinate and the second is y cordinates

x cordinates = -9

y cordinates = 4

To get the cordinates of the corresponding point for the function 4f(x)

4f(x) = 4 × f(x)

cordinates of 4f(x) = ( -9 × 4 , 4 × 4)

= ( -36, 16)

Therefore, the corresponding point on the graph 4f(x) is (-36,16)

Answer 2

The corresponding point would be (-36, 16)

Explanation:

To find this point, we simply need to multiply both points by 4.

-9 * 4 = -36

4 * 4 = 16
