Question

can I get some help

Answer 1

Which equation represents a linear function?

Equation 1: y3 = 2x + 1
Equation 2: y = 3x + 1
Equation 3: y = 5x^2 − 1
Equation 4: y = 4x^4 − 1

Equation 1

Equation 2

Equation 3

Equation 4

Answer 2

and with equation 1 y3 is y^3

Answer 3

any equation that has both Y and X without exponents (i.e. not x^3 or x^-3 for instance) and is just numbers (i.e. not fuctions like sin, log etc.) is a straight line (i.e. linear function)

Answer 4

so would it be equation 2
