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

Solution:

Given function is

f(a) = -2a² - 5a + 4

Now let's find f(-3)

For that we have to substitute -3 in the above equation,

f( -3) = -2(-3)² - 5(-3) + 4

By further calculation

= (-2 × 9) + 15 + 4

= 1

Therefore, f(-3) is 1.

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

Summary:

For the function f(a) = -2a² - 5a + 4, f(-3) is 1.
