Question

Given f(x) and g(x) = k⋅f(x), use the graph to determine the value of k.

−2
negative one half
one half
2

Answer 1

k = -2

Explanation:

Here Given that g(x) = k f(x)

From the graph we can observe that at x = -3 they gave the values of f(x) and g(x) which are

f(-3) = 1

g(-3) = -2

In the given equation substitute that x = -3

we get g(-3) = k f(-3)

on substituting the values we get

`-2 = k* 1`

k = -2
