Answer: A
Step-by-step explanation:
1x20=20
2x10=20
4x5=20
Are the 63x and the y being added or multiplied?
The answer is (f o g)(x) = 2x^2 - 13
In order to find a composite function, you take the first letter (in this case f) and use that equation. You then remove the variable and put in the second letter (g).
f(x) = 2x + 1 ----> Remove variable.
f(x) = 2( ) + 1 ----> Insert g(x)
(f o g)(x) = 2(x^2 - 7) + 1 ----> Distribute
(f o g)(x) = 2x^2 - 14 + 1 ----> Simplify
(f o g)(x) = 2x^2 - 13
Answer:
21 because there is a 1/4 chance and there are 84 questions, so 1/4 (25%) of 84 is 21.
