inverse of f(x)=(x+2)/7

Solution

inverse

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

Solution

7 x - 2

Solution steps

y = \frac{x + 2}{7}

Replace

x

with

y

x = \frac{y + 2}{7}

Solve for

y, x = \frac{y + 2}{7}

7 x - 2

Popular Examples

range of f(x)=-x+5 range

f (x) = - x + 5

inverse of (2x)/(2x-4)inverse

\frac{2 x}{2 x - 4}

parity f(x)=1+3x^2-x^4 parity

f (x) = 1 + 3 x^{2} - x^{4}

extreme f(x)=4x^{1/3}-x^{4/3}extreme points

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

intercepts of f(x)=-3(x-2)(x+5)intercepts

f (x) = - 3 (x - 2) (x + 5)
