Answer:
Explanation:
When asking for
they are basically asking you to evaluate the function
for -2, find a y value, and plug in that value as x in
Let's do it step-by-step:
1. Find the value of g(-2).
G(x) is given as a graph, therefore, you will have to see what value of axis y marks the graphic when you make x=-2. Check the attached image. As you may notice, the value that function g(x) generates for x= -2 is y= -3. Hence, g(-2)= -3.
2. Substitute the value into f(x).
F(x) is a piecewise function, so we'll need to determine the group the value fits into and calculate with the expession that corresponds for that value. Our value is -3, this value is less than -2, therefore, the function we'll have to use is
.
3. Determine the value of f(-3).
Since f(x)= 7 for our value (-3), the result is 7.
4. Express your answer.
