Step-by-step explanation:
<u>Step 1: Define</u>
g(x) = x³ - 4
h(x) = x² + 2
h(-2) is x = -2
g(-1) is x = -1
<u>Step 2: Find h(-2) - g(-1)</u>
- Substitute: ((-2)² + 2) - ((-1)³ - 4)
- Exponents: (4 + 2) - (-1 - 4)
- Add/Subtract: 6 - (-5)
- Subtract: 11

C.) The amount of money she saved before attending lessons.
A circle is not a function.
Nora is incorrect and her reason makes no sense.
Mia correct in her conclusion that a circle is not a function, but her reasoning is wrong. She confused her variables
I believe x= 32. 2(32) - 4 would equal 60. And due to all the angles and sides being the same, this would be correct.
36; Since, as shown by double lines, line BD and DC are the same (18) then the length of BC would be 36.
