Question

Which equations represent non linear functions select all that apply

Answer 1

y = 2x² - 13

y =
`5^x` + 1

Explanation:

The equations that represent non-linear functions are:

y = 2x² - 13

y =
`5^x` + 1

The other equations all represent linear equations. A linear equation is written in the form y = mx+b (slope-intercept form) where m is the slope and b is the y-intercept. All of the other equations given will simplify to this form when we isolate the y-variable.

y - 8 = x + 10 ➜ y = x + 18

y = -5x + 8

y + x = -1 ➜ y = -x - 1
