Question

How do you find any x-intercepts and y-intercepts. If no x-intercepts exist, state this.

g(x)=2x^2+3x-1

Answer 1

let y = 2x^2+3x-1

for y-intercept , let x = 0
That one is real easy

for x-intercept let y = 0
2x^2+3x-1 = 0
x = (-3 ± √17)/4
= ....

you do the arithmetic

Answer 2

2(x)+1=5
2(x)+1=5
2(x)=5-1
x=5-1/2
x=4/2
x=2
