Answer:

$f(x - 4) = x^2 - 6x+ 8$

Step-by-step explanation:

Given

$f(x) = x^2 + 2x$

Required

Find f(x - 4)

Substitute x - 4 for x

$f(x - 4) = (x- 4)^2 + 2(x - 4)$

Expand

$f(x - 4) = x^2 - 8x + 16 + 2x - 8$

Collect like terms

$f(x - 4) = x^2 - 8x + 2x+ 16 - 8$

$f(x - 4) = x^2 - 6x+ 8$

How to find 4x=14y and if it is parallel, perpendicular or neither to -2x+7y=14

RUDIKE [14]

4x = 14y
y = 4/14(x)
y = 2/7(x) slope = 2/7

-2x+7y=14
7y = 2x + 14
y = 2/7(x) + 2 slope = 2/7

parallel lines, slope is the same
both lines have slopes equal 2/7

answer
parallel
