Answer:
C
Step-by-step explanation:
(f + g)(x) = f(x) + g(x) , thus

= 2x + 1 + x² - 7 ← collect like terms
= x² + 2x - 6 → C

Answer:
c
Step-by-step explanation:
these two bars | | mean <u>absolute value</u>
here's how to find x
| x - 7| = 2
first apply the absolute rule
x - 7 = 2 x - 7 = -2
in both equations add 7 on both sides
x - 7 + 7 = 2 + 7 x - 7 + 7 = -2 + 7
then simplify the expressions
x = 9 x = 5
now combine these two solutions to get your answer
x = 9 or x = 5
