The lines y=-2 and y=-7 are they parallel, perpendicular, or neither?

parallel

Step-by-step explanation:

An equation of the form

y = k

where k is a number is a horizontal line.

Since both lines have the form y = k, with two different values of k, -2 and -7, these are two different horizontal lines, so they are parallel.

parallel

Parallel -inf to inf  

Step-by-step explanation:

there is no x value so they never cross

10

step-by-step explanation:

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
