Answer: 74
<u>Step-by-step explanation:</u>
Homework + Quiz + Test + Final Exam = 70
67(10%) + 62(15%) + 71(50%) + x(25%) = 70
6.7 + 9.3 + 35.5 + 0.25x = 70
51.5 + 0.25x = 70
0.25x = 18.5
x = 74
The minimum score is 74.
Answer:
2x^4+4x^2+2
Step-by-step explanation:
f(x) = x^2+1
g(x) = 2x^2
g(f(x))=
Replace x in the function g(x) with the function f(x)
=2( x^2+1)^2
= 2( x^2 +2x^2 +1)
= 2x^4+4x^2+2
