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:
(7x+2)(3x-1); (5x+4)^2 or (5x+4)(5x+4);
Step-by-step explanation:
formula to find area is L* W = A ; meaning length multiplied by width equals to the area.
21.
using the formula to find area...
l*w=a
(7x+2)(3x-1) would be your answer
btw, don't put the "=a" at the end, since it's an expression :))
22.
since the problem states that it's a square, you can just say either...
(5x+4)^2 or (5x+4)(5x+4) not sure which one your teacher accepts
14 ribbons.
7 divided by 1/2 is 14. dividing by a fraction or decimal is just like multiplying without the decimal point or numerator.
