Answer:

-6

30

22

8x² + 18x + 4

8x² - 2x - 6

Step-by-step explanation:

f(x) = 8x² + 2x - 6

f(0) = 8(0²) + 2(0) - 6 = -6

f(2) = 8(2²) + 2(2) - 6 = 32 + 4 - 6 = 30

f(-2) = 8 × (-2)² + 2(-2) - 6 = 32 - 4 - 6 = 22

f(x + 1) = 8(x + 1)² + 2(x + 1) - 6 = 8(x² + 2x + 1) + 2x + 2 - 6 = 8x² + 18x + 4

f(-x) = 8(-x)² + 2(-x) - 6 = 8x² - 2x - 6

Answer:

Step-by-step explanation:

when dividing numbers with exponents with the same base, subtract the exponents.

\frac{8^{7} }{8^{7} }

7 - 7 = 0

\frac{8^{7} }{8^{7} } = 8^{0}

anything to the power of 0 is 1

8^{0}= 1

15. (x - 3)<br> If f(x) = 2x2 – 5, find the following.<br> 16.fly-2)<br> 17. f(a+h)-f(a)
Masteriza [31]

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
