inverse of f(x)=2.4sqrt(x-0.3)+1.2

inverse

f (x) = 2.4 x - 0.3 + 1.2

0.17361 \dots x^{2} - 0.41666 \dots x + 0.55

Solution steps

y = 2.4 x - 0.3 + 1.2

Replace

x

with

y

x = 2.4 y - 0.3 + 1.2

Solve for

y, x = 2.4 y - 0.3 + 1.2

0.17361 \dots x^{2} - 0.41666 \dots x + 0.55

f (x) = x^{4} - 4 x^{3} + 3 x^{2}

9 x^{2} - 6 x - 3 x

f (x) = 3^{x - 2} + 1

\frac{7 x ^{2} + 8 x}{8 x ^{2} - 4}

f (x) = \frac{1}{x + 5}
