if x = 3
3 > -1, and so you use the x² formula.
Plug in 3 for x
x² = (3)²
Simplify
3² = 3 x 3 = 9
9, or (A), is your answer
hope this helps
Answer:
D.
Step-by-step explanation:
12x + 7x = 19x
-7 + +9 = 2

I got lazy to do the rest sorry :D
I think it could possibly be the 3rd one but I’m not too good with math
The inner function g(x) has x-13 in the denominator. Set it equal to 0 and solve for x
x-13 = 0
x-13+13 = 0+13
x = 13
If x = 13 then the denominator of g(x) will be zero. This is a problem since you cannot divide by zero
So x = 13 is not allowed as an input in the g(x) function. The same applies for the composite function as well.
So that's why the domain is the set of all real numbers x but x cannot equal 13
This translates to what choice D is saying, so that is the answer
