inverse of f(x)=2.1781x+25.2

inverse

f (x) = 2.1781 x + 25.2

\frac{x - 25.2}{2.1781}

Solution steps

y = 2.1781 x + 25.2

Replace

x

with

y

x = 2.1781 y + 25.2

Solve for

y, x = 2.1781 y + 25.2

\frac{x - 25.2}{2.1781}

f (x) = 0.577

(1, - 3), (5, - 1)

f (x) = 5

X^{3}

y = \frac{9}{5} x + 35
