Question

answer g: 4
#3 evaluate f(-8) - f(4).
graph of f(x) with grid
answer k: 5

answer h: 7
evaluate 3g(7) - 1.
graph of g(x) with grid
answer l: -13

Explanation:

For the problem: Evaluate $f(-8)-f(4)$

Step1: Find $f(-8)$ from the graph

From the leftmost segment of the $f(x)$ graph, when $x=-8$, $f(-8)=-6$.

Step2: Find $f(4)$ from the graph

From the $f(x)$ graph, when $x=4$, $f(4)=7$.

Step3: Compute the difference

Substitute the values into the expression: $f(-8)-f(4) = -6 - 7$

Step1: Find $g(7)$ from the graph

From the $g(x)$ graph, when $x=7$, $g(7)=4$.

Step2: Calculate $3g(7)$

Multiply the value by 3: $3g(7) = 3 \times 4 = 12$

Step3: Subtract 1 from the result

Subtract 1 from the previous value: $3g(7)-1 = 12 - 1$

Answer:

$-13$
