Find the xand y-intercepts.

y=-5x2-30x-46

Short Answer

Expert verified

No x-intercepts.

They-intercepts is0,-46.

Step by step solution

01

Step 1. Given information.

The given equation is y=-5x2-30x-46.

02

Step 2. Determine the x-intercepts.

Substitute y=0in the given equation.

y=-5x2-30x-460=-5x2-30x-46

Here,a=-5,b=-30,c=-46.

Find the value of discriminant to predict the nature of solution.

b2-4ac=-302-4-5-46=900-920=-20<0

From the above result, no real solution exists.

Hence, there are nox-intercepts.

03

Step 3. Determine the y-intercepts.

Substitute x=0in the given equation.

role="math" y=-5x2-30x-46=-502-300-46=-46

Hence, the requiredy-intercepts is0,-46.
