Question

What is f(−3) for the function

f(a)=−2a−5a+4?

A. -29
B. -23
C. 1
D. 37

Answer 1

To find f(-3) for the function f(a) = -2a - 5a + 4, substitute -3 in place of a and simplify the expression. The result is 25.

Step-by-step explanation:

To find f(-3) for the function f(a) = -2a - 5a + 4, we substitute -3 in place of a:

f(-3) = -2(-3) - 5(-3) + 4

Now we simplify the expression:

f(-3) = 6 + 15 + 4

f(-3) = 25

Therefore, f(-3) is equal to 25. So the correct answer is None of the above.
