Answer:
B. f(x)
D. h(x)
Step-by-step explanation:
An exponential function will have a common ratio.
We check and see if the consecutive terms has a common ratio.
For f(x),
[tex] \frac{5}{2} \ne \frac{10}{5} [/tex]
This is not an exponential sequence.
For g(x), we have:
[tex] \frac{2}{1} = \frac{4}{2} = \frac{8}{4} = 2[/tex]
For h(x),
[tex] \frac{1.25}{1} \ne \frac{1.5}{1.25} [/tex]
This is not an exponential sequence
For k(x),
[tex] \frac{16}{64} = \frac{4}{16} = \frac{1}{4} = \frac{0.25}{1} [/tex]
Using the concept of exponential function, it is found that the following function is not exponential:
D. h(x)
- If the absolute value of the change is always the same, it is linear.
- If the rate is the same, it is exponential.
In this problem:
- In functions f, g and k, when x changes by 1, y is multiplied by a value, hence the rate is the same, as they are exponential.
- In function h(x), when x changes by 1, y changes by 0.5, hence the absolute value of the change is the same, and it is linear, hence option D is correct.
