Does the rule y = 2 · x + 4 represent a linear or an exponential function? Explain.

A.

Linear function; the function is in the form y = abx, where a ≠ 0, b > 0, b = ≠ 1, and x is a real number.

B.

Linear function; the independent variable x is not an exponent.

C.

Exponential function; the function is in the form y = mx + b, where m = slope, b = y-intercept, and x is a real number.

D.

Exponential function; the function is in the form y = abx, where a ≠ 0, b > 0, b = ≠ 1, and x is a real number.
