Question

When comparing linear, quadratic, cubic, and exponential functions, what key feature do the all four function types share?(1 point)

The x-intercept of all four function types is (0,0)
.

The range of all four function types is all real numbers.

The domain of all four function types is all real numbers.

The minimum value of all function types is (0,0)
.

Answer 1

The domain of all four function types is all real numbers.
All polynomials (linear, quadratic, cubic) and exponentials are defined for every real x, so their domain is (-∞, ∞).
