The graph of the function f(x)=3(2)^x -4 passes through the points (0,-1), (1,2), (2,8) and (3,20)
<h3>What are exponential functions?</h3>
When the expression of function is such that it involves the input to be present as exponent (power) of some constant, then such function is called exponential function.
here usual form is specified below. They are written in several such equivalent forms.
The equation of the function is given as:
Set x = 0, 1, 2 and 3
This means that the graph of the function f(x) = 3(2)^x -4 passes through the points (0,-1), (1,2), (2,8) and (3,20).

To convert 1.3 miles into inches we proceed as follows;
1 mile=63360 inches.
Therefore the number of inches in one mile will be as follows:
(1.3*63360)
=82,368 inches
Therefore, we conclude that our answer is 82,368 inches.
2x + 3y = 36
2x + 3*6 = 36
2x + 18 = 36
-18 -18
___________
2x = 18
/2 /2
___________
x = 9
Answer:
Step-by-step explanation:
This relation (this group of points) is NOT a function. In order to be a function, every x-value (the first number in the pair) can only be paired up with one y-value (only one partner for the x)
In this relation, -6 is paired up with four different y-values (four different partners!)
If you plotted these points on a graph, you would see they are all lined up in a vertical line. If you have learned about the vertical line test, you will see that a vertical line goes through all four points. This set of points fails the vertical line test. To be a function, a vertical line can only touch the points one at a time.
To be a function, every x can only have one y partner.
