What is g(k+1)=x^2-4x

g(k + 1) = k² - 2k - 3

Step-by-step explanation:

Step 1: Plug in (k + 1) in for x

g(k + 1) = (k + 1)² - 4(k + 1)

Step 2: FOIL

g(k + 1) = k² + 2k + 1 - 4(k + 1)

Step 3: Distribute

g(k + 1) = k² + 2k + 1 - 4k - 4

Step 4: Combine like terms

g(k + 1) = k² - 2k - 3

c. (3,2,6) is the answer.

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
