Question

Which function is a linear function a. 1-3x^2 b. y+7=5x c. x^3 + 4 = y d. 9(x^2-y) = 3 e.y-x^3=8

Answer 1

b. y+7=5x

Explanation:

a. 1-3x^2 is a quadratic

b. y+7=5x is a linear function: y = 5x - 7

c. x^3 + 4 = y is a cubic function

d. 9(x^2-y) = 3 is a quadratic function

e.y-x^3=8 is a cubic function
