inverse of f(x)=7x^2-10

inverse

f (x) = 7 x^{2} - 10

\frac{x + 10}{7}, - \frac{x + 10}{7}

Solution steps

y = 7 x^{2} - 10

Replace

x

with

y

x = 7 y^{2} - 10

Solve for

y, x = 7 y^{2} - 10

\frac{x + 10}{7}, - \frac{x + 10}{7}

f (x) = \frac{x}{x ^{3} - 1}

f (x) = \frac{4 x}{x - 3}

\frac{x ^{2} + 7 x + 12}{x ^{2} + x - 6}

f (x) = 100 - x^{2}

f (x) = x - 2 + 1
