Answer:

You could use a graphing calculator to see the lowest point in the graph OR you could put that equation into it's completed squared form, which is (x-4)^2 -4. The opposite of -4 in the parentheses is positive 4, and the leftover -4 is the y value. So that also becomes (4,-4)

Y=8(x^2+4)+17+-32 in vertex form

Yakvenalex [24]

$y = 8( {x}^{2} + 4) + 17 + ( - 32)$
$y = 8( {x}^{2} + 4) + 17 - 32$
$y = 8 {x}^{2} + 32 + 17 - 32$
$y = 8 {x}^{2} + 17$
compare to the formula:
$y = a( {x}^{2} - h) + k$
$y = 8( {x}^{2} - 0) + 17$
a = 8
h = 0
k = 17

How to solve shaded regions on a trapezoid is simple.
First find the area of the whole trapezoid, or W but it already gives us that as 21.66 in squared.
Next, find the area of the non shaded region, or NS.
3.8*4.6=17.48 in
Lastly, subtract the NS from the W.
21.66 -17.48 =
NS= 17.48 in squared.
W= 21.66 in squared.
S= 4.18 in squared.

The answer is B- 4.18 in Squared
