Answer: the maximum is 25.
Step-by-step explanation: a max/min can occur on the endpoints of a function and critical points of the function's derivative.
f(x)=x^4-x^2+13
f'(x)=4x^3-2x
The critical points of f'(x) occur when f'(x) is zero or undefined. f'(x) is not ever undefined in this case, so we just need to find the x values for when it's zero.
0=4x^3-2x
x=.707, -.707
Now that we have the critical points of f'(x) (.707 and -.707) and endpoints (-1 and 2), we can plug in these x values into the original function to determine its maximum. When you do this you'll find that the greatest y value produced occurs when x=2 and results in a max of 25.

Step-by-step explanation:
Answer:
Q19 - x = 7
Q20 - x = 24
Step-by-step explanation:
Q19.
75 + x + 8 = 90°
83 + x = 90°
x = 90 - 83
<u>x = 7</u>
<u>{</u>CHECK: 75 + 7 + 8 = 90°<u>}</u>
<u></u>
Q20.
3x - 6 + x = 90°
4x - 6 = 90°
4x = 96
x = 96 / 4
<u>x = 24</u>
<u>{</u>CHECK: 3(24) - 6 + 24 = 90°<u>}</u>
<u></u>
