Question

TEACHER:
A. TRUE OR FALSE. Tell whether each statement is true or false. Write your answer on the blank.
1. f(x) = 3x² is an exponential function.
2. If f(x) = 2*, then f(-1) = 2.
3. The graph of a function is either concave up or concave down.
4. Every exponential function has a vertical intercept.
5. Every exponential function has a horizontal intercept,
6. The function f(x) = 1* is an exponential function.
7. An exponential function of the form f(x) = k at will always pass through the point
(0, 1)
8. The exponential function y = 3.()* could be an appropriate model for exponential
growth
9. The graph of f(x) = 5* - 1 shifts the graph of f(x) = 5* one unit to the left.
10. The function f(x) = ( (1/3)) ^x and g(x) = 3* have the same graph.​
