Question

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

A. -5
B. -1/5
C. 1/5
D. 5​

Answer 1

Answer:

$k=-5$

Step-by-step explanation:

If we observe the graph carefully there are two on each of the graphs highlighted at x=-2.The functions take the following values at that x.

$f(-2)=2$

$g(-2)=-10$

given the condition

$g(x)=k*f(x)$

put $x=-2$

we get . $-10=k*2$

$k=-5$
