Answer:
b = 18
Step-by-step explanation:
1st step is isolating b by moving 2 to the other side. When you move a number the the other side it flips (from + to - or × to ÷). The 2 in this question is being multiplied my b (no sign means multiply) so when you move it to the other side it becomes 36/2 or 18
Steps:
2b=36
b=36/2
b=18

Find constant a.
----------------------------------------------------------------------------
Given that g(4) = 8
--------------------------------------
Substitute x = 4
--------------------------------------
g(4) = a(4)² + 24 = 8
16a + 24 = 8
--------------------------------------
Take away 24 from both sides
--------------------------------------
16a = 8 - 24
16a = -16
--------------------------------------
Divide by 16 on both sides
--------------------------------------
a = -1
Now that we know that a = -1, plug it back to the equation.
g(x) = -x² + 24
--------------------------------------
Find g(-4)
--------------------------------------
g(-4) = - (-4)² + 24
g(-4) = -16 + 24
g(-4) = 8
