Find vertical axis horizontal axisslope x intercept and y in
Find vertical axis, horizontal axis/slope, x intercept and y intercept.
2x^2+x-6/x^2+3x+2
Solution
y = (2x^2+x-6)/(x^2+3x+2)
x intercept plug y = 0
0 = (2x^2+x-6)/(x^2+3x+2)
2x^2+x-6 = 0
(x+2)(2x-3) = 0
x = -2 , x = 3/2 ----- x intercepts
y intercept , plug x = 0 in the function
y = (2x^2+x-6)/(x^2+3x+2)
y = -6 / 2 = -3
y = - 3 ( y intercept )
vertical asymptotes
set denominator = 0
x^2+3x+2 = 0
x = -1 ( vertical asymtote)
horizontal asymptote
y = coefficient of x^2 in numerator / coefficient of x^2 in denominator = 2 / 1
y = 2 ( horizontal asymtote)
