Question

-3•f(-8)+7•g(2)=??????????

Answer 1

The value of given expression is -22.

Explanation:

We are given attached graph with the question.

The graph consist of plot for two function y = f(x) and y= g(x).

We need to evaluate the value of expression:

`-3* f(-8) + 7* g(2)`

From the given graph, it is easy to calculate value for f(-8) and g(2).

From graph:

f(-8) = -2

g(2) = -4

These values were obtained by looking the corresponding y-value for given x-values from the graph.

Putting the values in the expression, we get:

`(-3)* (-2) + 7* (-4) = 6 - 28 = -22`

Hence, the value of given expression is -22.

Answer 2

-22

Explanation:

-3•f(-8)+7•g(2)=

The value of f(x) at x=-8 is

f(-8) = -2

The value of g(x) at x=2 is

g(2) = -4

Substituting these values into the equations

-3 * -2 +7*-4

6 -28

-22
