Answer:
He is correct
Step-by-step explanation:
multiplication and division are inverse operations so lets divide to see if he is correct
40.7/10=4.07
he is correct
The statement that -6 is in the domain of f(g(x)) is true
<h3>Complete question</h3>
If f(x) = -2x + 8 and g(x) =
, which statement is true?
- -6 is in the domain of f(g(x))
- -6 is not in the domain of f(g(x))
<h3>How to determine the true statement?</h3>
We have:
f(x) = -2x + 8

Start by calculating the function f(g(x)) using:
f(g(x)) = -2g(x) + 8
Substitute 

Set the radicand to at least 0

Subtract 9 from both sides

This means that the domain of f(g(x)) are real numbers greater than or equal to -9. i.e. -9, -8, -7, -6, ...........
Hence, the statement that -6 is in the domain of f(g(x)) is true

Answer:
C
Step-by-step explanation:
12 divided by 3 is 4 and 30 divided by 3 is 10
If the zeros are -2 and 3, then the factored form would be
(x+2) and (x-3)
-2+2 = 0 and 3-3 = 0
A polynomial is written as ax^2 + bx + c
Expand (x+2) (x-3) using FOIL: Multiply each tern in one set of parenthesis by each term in the other set and then simplify by combining like terms:
x*x + x*-3 + 2*x + 2*-3
x^2 -3x + 2x -6
Polynomial in standard form:
x^2 -x -6
