Which of the following is the function representing the graph below?
1 answer:
You need to pick a point on the graph, then go through the list of choices
and see which one can produce the point you picked.
Look at the point on the graph right above the origin, where the graph
crosses the y-axis. At that point, x=0 and f(x) (or 'y') = 1 .
Now look at the choices, one at a time, and see whether (0, 1) fits.
I'll start at the bottom of the list:
--> <u>f(x) = 4^(x-3)</u>
When x=0, f(x) = 4^(-3) .
4^(-3) is not '1', so our point is not on this f(x).
--> <u>f(x) = 4^x + 3</u>
When x=0, f(x) = 4⁰ + 3 = 1 + 3 = 4
'4' is not '1', so our point is not on this f(x).
--> <u>f(x) = 4^x - 3</u>
When x=0, f(x) = 4⁰ - 3 = 1 - 3 = -2
'-2' is not '1', so our point is not on this f(x).
(Only one choice left.)
--> <u>f(x) = 4^x</u>
When x=0, 4^x = 4⁰ = 1
That's it ! Our point is on this f(x).
Which is lucky, because we were out of choices.

Answer:
60% x 25
55 % x 25
10 in english
25 is total and rest will be math
so 25-10 = 15

Answer:
$34.49
Step-by-step explanation:
To figure out this problem, you would need to divide the total price by the total amount of items you are buying
In this case it is...
172.45/5
=34.49
So the price of each item is approx. $34.49
Answer:
18x
Step-by-step explanation:
get the x by itself then it is 2+4=6 so that is 6x and then do 3+x=3x and 6x×3x= 18x
