Answer:
16. f(y-2) = 2(y-2)²-5
= 2(y²-4y+4)-5
= 2y²-8y+8-5
= 2y²-8y+3
17. f(a+h)-f(a) = 2(a+h)²-5-(2a²-5)
= 2(a²+2ah+h²)-5-2a²+5
= 2a²+4ah+h²-2a²
= h²+4ah
Range. Range is the difference between the largest and smallest number in a set of numbers.

Answer:
x = 6
Step-by-step explanation:

6( - 4 ) = 30 ( divide both sides by 6 )
- 4 = 5 ( add 4 to both sides )
= 9 ( multiply both sides by 2 to clear the fraction )
3x = 18 ( divide both sides by 3 )
x = 6
