Solution

inverse

y = - 2 x - 1

Solution

- \frac{x + 1}{2}

Solution steps

y = - 2 x - 1

Replace

x

with

y

x = - 2 y - 1

Solve for

y, x = - 2 y - 1

- \frac{x + 1}{2}

2 x^{3} - 3 x^{2} - 36 x

asymptotes of f(x)= 2/(x^2+3x)asymptotes

f (x) = \frac{2}{x ^{2} + 3 x}

domain of f(x)=((5x-5))/((x^2-1))domain

f (x) = \frac{( 5 x - 5 )}{( x ^{2} - 1 )}

intercepts of f(x)=x^2+3x+1/4 intercepts

f (x) = x^{2} + 3 x + \frac{1}{4}
