Create a graph that has the following intercepts. Make sure to label each of the intercepts onthe graph, as well as the axis on your graph.
y=-3, x = 5, y = 3

Answers

Answer:

see below for the graph

Step-by-step explanation:

The desired graph has two y-intercepts and one x-intercept. It is not the graph of a function.

Here's one way to get there.

Start with the parent function y = |x| and scale it down so that it has a y-intercept of -1 and x-intercepts at ±1.

Now, it is ...

f(x) = |x| -1

We want to scale this vertically by a factor of -5. this puts the y-intercept at +5 and leaves the x-intercepts at ±1.

Horizontally, we want to scale the function by an expansion factor of 3. The transformed function g(x) will be ...

g(x) = -5f(x/3) = -5(|x/3| -1) = -5/3|x| +5

This function has two x-intercepts at ±3 and one y-intercept at y=5. By swapping the x- and y-variables, we can get an equation for the graph you want:

x = -(5/3)|y| +5

Comment on this answer

Since there are no requirements on the graph other than it have the listed intercepts, you can draw it free-hand through the intercept points. It need not be describable by an equation.

Answer:

x = 12

Step-by-step explanation:

$(x)/(-4) = -3$

To solve this equation, simply take the denominator from the fraction on the left side of the equation to the right side of the equation and multiply it with the constant.

Also, do not forget to multiply the signs as both the numbers are negative so the number will become positive after multiplication:

$x = -3$ × $(-4)$
