Question

Which of the following functions shown in the table below could not be an exponential function?

Answer 1

@triciaal @satellite73

Answer 2

I answered already

Answer 3

an exponential function has to basically increase or decrease very fast.

Answer 4

The only two function that do this are g(x), and k(x).

Answer 5

@triciaal is a differ one?

Answer 6

same type question means same process different numbers

exponential function basically means the difference in the y value is not changing by the same amount as x changes from one number to the next consecutive number. in addition to that as stated by @rosho as well, the amount of change between the y values is a large amount

an example:think of change in population for a particular town over a period of years
example the square of numbers x = 1, 2, 3 ,4 corresponding y = 1, 4 9, 16

Answer 7

do you see h(x) is not exponential because for every change in x the change in y is the same ?

Answer 8

so g(x) and k(x)?

Answer 9

no, read carefully

Answer 10

h(x)?

Answer 11

correct

Answer 12

you you understand what an exponential function is now?
plot the points for x^2 given in the example and see how the graph looks
