The value of function f(x). =-2ax² -5a + 4 at a = -3 will be -23a + 2.

<h3>What is a function?</h3>

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

For example y = sinx ,  y = x + 3 ets.

Given,

f(x)  = - 2ax² -5a + 4

x = -3

f(-3) =  - 2a(-3)² -5a + 4

f(-3) = -18a - 5a + 4

f(-3) = 23a + 2

Hence the value of function f(x). =-2ax² -5a + 4 at a = -3 will be -23a + 2.

Answer:

I'll assume f(a). =-2ax2-5a+4 is supposed to read f(a) = -2a<u>^2</u>-5a+4.  There is no definition of "x" in this problem.

If so, f(-3) = 1

Step-by-step explanation:

f(a) =-2ax^2-5a+4

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

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

f(-3) =-18 + 19

<u>f(-3) =  1</u>
