Question

What is f(–3) for the function f(a) = –2a2 – 5a 4?

Answer 1

Answer:

the value of f(-3) is 1.

Step-by-step explanation:

(-3)

f(a) = -2a² - 5a + 4

Substitute a with its value, -3

f(-3) = -2(-3²) - 5(-3) + 4

f(-3) = -2(9) + 15 + 4

f(-3) = -18 + 19

f(-3) = 1

the value of f(-3) is 1.

Answer 2

F(-3)
f(a) = -2a² - 5a + 4

Substitute a with its value, -3

f(-3) = -2(-3²) - 5(-3) + 4
f(-3) = -2(9) + 15 + 4
f(-3) = -18 + 19
f(-3) = 1

the value of f(-3) is 1.
