Tju [1.3M]

Answer:

All Real Numbers except for 4

Step-by-step explanation:

Objective: Specify domain and range of a function.

The equation is a linear equation. A linear equation range is all real numbers. However x cannot equal 1 so let plug in x to find where the y value CANT be.

$f(1) = 1 + 3 = 4$

So the range is

All Real Numbers except for 4.

A line has a slope of -3 and a rise of 21, what is the run?

grigory [225]

Answer:

The run is -7.

Step-by-step explanation:

Since we know that slope = rise/run, we can calculate the run by inputting the given numbers.

So,

-3 = 21/x and we need to solve for x.

When we cross multiply we get -3x=21.

Then, divide -3 on both sides and x = -7
