Answer:
A. 76
B. x^2 +21x + 96
C. x^2 - 9x + 6
Step-by-step explanation:
For this problem, just plug in the number in f(x) for x in the function.
A. f( 5 ) -> Plug in 5 for every x and then simplify
(5)^2 + 9(5) + 6
= 25 + 45 + 6
= 76
B. f( x+6 ) -> Plug in (x+6) for every x and then simplify
(x+6)^2 + 9(x+6) + 6
x^2 + 12x +36 + 9x+ 54 + 6
x^2 +21x + 96
C. f( -x ) -> Plug in -x for every x and then simplify
(-x)^2 + 9(-x) + 6
x^2 - 9x + 6

A clock has 12 hours on it.
360/12 = 30
Each hour is 30 degrees.
3pm to 7:30pm is 4.5 hours
Multiply total hours by degrees per hour:
4.5 x 30 = 135 degrees
