Which function has a range of y < 3? y = 3 (2) Superscript x y = 3 (3) Superscript x y = negative (2) Superscript x Baseline
+ 3 y = (2) Superscript x Baseline minus 3
1 answer:
Answer:
y = negative (2) Superscript x Baseline + 3
Step-by-step explanation:
An exponential function has a range of y > 0. In order for it to have a range of y < 3, it must be reflected across the x-axis (given a negative multiplier) and must be translated upward 3 units.
That is, for some exponential function y = b^x, you must have something of the form ...
y = -a·b^x +3
Only one answer choice has this form:
