Hello :
f(x) = 4(x2 − 6x + 3² - 3²____) + 20 = 4((x2 − 6x + 3²) - 3²____) + 20<span>
= 4(x-3)² -36+20
</span>f(x) = 4(x-3)² -16 (vertex form)
G(h(0)) = 20
h(x) = x+4
h(0) = 0+4
h(0) = 4
g(x) = 5x
g(h(0)) = g(4) = 5(4) = 20

Answer:slope = 7/8
Explanation:Slope of the line can be calculated using the following equation:
slope =

The two points given are:
(2,5) representing (x1 , y1)
(-6,-2) representing (x2 , y2)
Substitute with the points in the above equation to get the slope as follows:
slope =

= 7/8
Hope this helps :)
