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.

Domain of 2(x + 5) is all real numbers.
Answer:
angle Z=20°
side xy≈15.36
hypotenuse≈19.49
Step-by-step explanation:
Find angle z adding the other two angles and subtracting that by 180 to get 20.
(12)tan(20) gets you side xy which is 15.36
12^2+15.36^2=xz^2
Answer:
![-\frac{3}{7}](https://tex.z-dn.net/?f=-%5Cfrac%7B3%7D%7B7%7D)
Step-by-step explanation:
The additive inverse of a number (its "opposite") is what you add to the given number to get a sum of zero.
![\frac{3}{7} + (-\frac{3}{7}) =0](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B7%7D%20%2B%20%28-%5Cfrac%7B3%7D%7B7%7D%29%20%3D0)
