These are "composite" functions.
g(x+a) means insert (x+a) into g(x) to replace every x:
g(x+a) - g(x) = -5(x+a)^2 +4(x+a) +5x^2 - 4x
= -5(x^2 + 2ax + a^2) +4x +4a + 5x^2 - 4x
Now just Multiply and sum up the answer.
Answer:
T and F
Step-by-step explanation:
Hi! Maybe I am reading it wrong, but only 2 statements are given. The answer to these statements are true and false.
"A square root of 16 is 4."

4 squared, or 4 * 4 is equal to 16, and therefore this is true.
"The only square root of 9 is -3."
This is false. 9 has 2 square roots: 3 and -3.
3 * 3 = 9, and so does (-3) * (-3).
So we have T and F, which eliminates the second, third, and fourth choices, which means even without a last statement, A is your correct answer.
Hope I helped! :)
