f(x)= -2x^3+10x^2+48x



Find all x and y intercepts of the graph of the polynomial function​

step 1

Find the y-intercept

Remember that

the y-intercept is the value of the function f(x) when the value of x is equal to zero

so

For x=0

f(x)= -2(0)^3+10(0)^2+48(0)

f(x)=0

so

the y-intercept is 0

step 2

Find the x-intercepts

Remember that

The x-intercepts are the values of x when the value of the function f(x) is equal to zero

so

For f(x)=0

using a graphing tool

Find the x-intercepts

see the attached figure to better understand the problem

please wait a minute

the x-intercepts are -3,0 and 8

F(x)= -2x^3+10x^2+48xFind all x and y intercepts of the graph of the polynomial function-example-1
