# How do you find the vertex and the intercepts for #y= -3(x-1)(x+5)#?

##### 1 Answer

Vertex is at

Intercepts at

#### Explanation:

From the given

Expand the right side so that it will take the form

Now it takes the form

with

We can now solve for the vertex

Vertex

To solve for the intercept, let us use the given

Solve for x-intercept by setting

Equate both factors to 0

First factor

Second factor

Use again the original equation

there is an intercept at

The graph of

vertex

graph{y=-3(x-1)(x+5)[-60,60,-30,30]}

God bless .... I hope the explanation is useful.
