Question

Which of the following functions is not a linear function?

A.) f(x) = -2

B.) f(x) = x - 2

C.) f(x) = 2x

D.) f(x) = x 2

Answer 1

any function with an exponent is not linear

Answer 2

linear means can be written in the form \[y=mx+b\] where \(m,b\) are constants.

Answer 3

@Mehek14 y=2x+3^2 is linear.

Answer 4

@Mehek14 \(y=2^2x+3\) is linear

Answer 5

the variable not slope

Answer 6

Then whats the answer?

Answer 7

y=mx+b is linear so if you have an exponent in the equation the line is no longer a line with a slope but a parabola
