inverse of f(x)=21x^3-28

inverse

f (x) = 21 x^{3} - 28

3 \frac{x + 28}{21}

Solution steps

y = 21 x^{3} - 28

Replace

x

with

y

x = 21 y^{3} - 28

Solve for

y, x = 21 y^{3} - 28

3 \frac{x + 28}{21}

f (x) = 3 x + 9 - 2

f (x) = \frac{3 x - 4}{5 x + 6}

f (x) = a (r) = 3 r + 15

f (x) = \frac{4 x}{3 x - 1}

f (x) = \frac{3 x + 1}{11 x - 2}
