Question

When comparing linear, quadratic, and exponential functions, what key feature do all three function types share? (1 point)
• The domain of all four function types is all real numbers
• The minimum value of all function types is (0,0)
• The range of all four function types is all real numbers
• The x-intercept of all four function types is (0,0)

Answer 1

"The domain of all four function types is all real numbers" — (interpreting "four" as "three") is correct.

Linear (ax + b), quadratic (ax^2 + bx + c), and exponential (a·b^x) are all defined for every real x, so their domain is all real numbers.
