inverse of f(x)=7x^2-2

inverse

f (x) = 7 x^{2} - 2

\frac{x + 2}{7}, - \frac{x + 2}{7}

Solution steps

y = 7 x^{2} - 2

Replace

x

with

y

x = 7 y^{2} - 2

Solve for

y, x = 7 y^{2} - 2

\frac{x + 2}{7}, - \frac{x + 2}{7}

f (x) = \frac{5}{9} (x - 32) + 273.15

f (x) = \frac{( 2 x + 5 )}{( x + 7 )}

y = 2^{c o s (x)}

- \frac{1}{2} (x + 3)

\frac{x}{2 x + 3}
