Question

What function has a y-intercept of 1/2?

Answer 1

Slope intercept form
y = mx + b where m is the slope and b is the y-intercept

Y-intercept: the y-value when x=0

Answer 2

out of \[f(x)=\frac{ 2 }{ (2x-1)(x+1) }\]
\[f(x)=\frac{ 2 }{ 2x ^{2}+5x-3 }\]
\[f(x)=-\frac{ 4 }{ x ^{2}-7x-8 }\]

Answer 3

plug x=0, u will get the y-intercept value

Answer 4

thanks you guys!
