(a) Using the table, give the values fo rthe inverse

1) original table of values:

x      1     2     3    4    5

f(x)   0     1     1    5    3


2) The inverse of the function is obtained by exchanging x and f(x), this is:

                   ( x, f(x) ) → ( f(x), x)

3) So, the table of values of the inverse of the given function is:

x          0    1     1      5     3

f⁻¹ (x)   0     1     2     3     4

(b) Is the inverse a function.

No, the inverse is not a function, since the table of the inverse shows that the x -value 1 has two different images.

This ambigüity is opposite to the definition of a function, which requires that any input value has only one output. For that reason, the inverse is not a function. You cannot tell whether the image of 1 is 1 or 2, because both are images of the same value.

Which of the following is an equation of a proportional relationship?
Alborosie

Answer:

Both are proportional, because as the value of x change (increases or decreases), the value of y changes (increases or decreases).

The first equation (y = 25x) could represent that amount of teachers per students. If x = teachers (let's say there is 1 teacher), then y = students (1 teacher would teach a class of 25 students).

The second equation (y = 5x + 25) could represent the amount of money you could earn babysitting. The starting/base amount would be $25, and you would earn $5 more for every hour you babysat.

How can you use the distributive property to check your work when factoring?
Anestetic [448]
A factor is any number that can be divided into another number evenly. When factoring, we look for common factors within a math expression. Factoring is normally used when finding common factors. The beauty of finding common factor is that it allows us to apply the distributive property usually applies multiplication to an existing mathematical expression such as an addition statement. This means that a number that is outside the parenthesis of an addition problem can be multiplied by each of the numbers inside the parenthesis. The opposite case is; a common factor can be factored out and written outside the parenthesis.
