If you are doing a simple version, it goes up by 2, then 4, then 6, then 8. So the next ones are 31, 43, 57
<u>Answer:</u>
f(x) = 7 is an even function.
<u>Step-by-step explanation:</u>
Any function is even when
and gives a graph that is symmetric with respect to the y-axis.
We are given these options and we have to check whether which of them is an even function:

and
- This function is not even

and
- This function is not even

and
- This function is not even

and
- EVEN FUNCTION
We get the same value for
and
, therefore f(x) = 7 is an even function.
I think the it would be some like y-8
Given the
function f(x) = 10000(0.73)^x
<span>Where y
is The value of a boat, in dollars, </span>
<span>x
years after its purchase </span>
at x = 1
f(1) = 10000(0.73)^1
f(1) = $7300
at x = 2
f(2) = 10000(0.73)^2
f(2) = $ 5329
so the decrease
D = $7300 - $ 5329
D = $ 1971
