A function is an equation or graph where each x value only has one y value. In the first image you can use the vertical line test. Take your pencil and lay it on the paper vertically. Move it across the graph. Basically if an x value has multiple y value it is not a function. The first image is not a function because all x values past zero have multiple y values for each x value. In the second image it is not A because in A the x value of 2 has a y value of 1 and 8. It is not B because the 5 has a y value of 3 and 7. It’s is not D because of the 5 again. It is C because all x values are unique.
Hope that helps
Answer:
In each place there must be more 100 pennies, but as the total 250 pennies, there are several ways that the money is distributed.
Because there may be 101 pennies in the box and 149 pennies in the bank, but it can also be the opposite; in the box 149 pennies and in the bank 101 pennies.
Therefore, there are many options to answer the question, as long as it is met that there are more than 100 pennies in one place.
Answer:
D)- Less than 1 Mile
Step-by-step explanation: as current= 1 1/2 Miles = 3/2 Miles
Total plans= 2 1/3= 7/3 Miles
Difference= (7/3)-(3-2)
= 5/6 Miles
Problem
evaluate the function
f(-x) = f(x)
plug in the points (2,1) then solve
Solution
For this case we can conclude that:
f(2) =1
So then we satisfy that:
f(-2) =1
