There are three elements in that set.
The inverse of the function is f(x) = + 8
In order to find the inverse of any function, start by switching the f(x) and x. Then solve for the new f(x). The result will be the inverse function. The work is below for you.
f(x) = ----> Switch f(x) and x
x = ----> Cube both sides
= f(x) - 8 ----> Add 8 to both sides
f(x) = + 8
The graph represents a function but the table does not. The reason for this is that one input value (70) in the table is associated with two output values (54.6 and 53.11), which is a sure sign that we do NOT have a function here.
Answer:
slope = 4
Step-by-step explanation:
We can find the slope of a line when knowing 2 points by using the slope formula, . and represent the x and y values of the first point, respectively. and represent the x and y values of the second point, respectively.
The two points we have are (2,8) and (0,0). So, in this case, = 2, = 8, = 0, and = 0. Let's substitute those values into the formula and solve to get the slope:
So, the slope is 4.
There are 3 girls .
9 students , 3 boys & 3 girls + another 3 boys because there are 3 more than girls so there are only 3 girls since you can't exceed 9 .
