Afunction is shown below. what is the value of the expression f(-3) + 2f(-1) - f(4) ? *show work* ((explain it to me))

a. 101/36

b. 32/9

c. 4

d. 22

OPTION D: 22

Step-by-step explanation:

Choose the function value according to the domain given.

To find f(-3) :

f(x) = x² + 2x for x ≤ -3

That means for those values of x, less than or equal to -3, this is the function.

So, f(-3) = (-3)² + 2(-3) = 9 - 6 = 3

Now, f(-1) :

From the given data, we see it is: f(x) = 2

We take this because -1 lies between -3 and 4.

Now, f(-1) = 2

18

For f(4) :

Clearly, the function is:

f(4) = -1

Therefore, f(-3) + f(-1) - f(4) = 3 + 18 - (-1) = 3 + 18 + 1 = 22, which is OPTION D.

after simplifying it i got: -36.25 as my answer. hope that !

8 2/3 is the answer

step-by-step explanation: just use a calculator
