Finding the inverse function for f(x)=1/x^2

Anna [14]

to get the inverse of any expression, we start off by doing a quick switcheroo on the variables and then solve for "y".

$\stackrel{f(x)}{y}=\cfrac{1}{x^2}\implies \stackrel{\textit{quick switcheroo}}{x=\cfrac{1}{y^2}}\implies y^2=\cfrac{1}{x}\implies y=\sqrt{\cfrac{1}{x}}\implies \stackrel{f^{-1}(x)}{y}=\cfrac{1}{\sqrt{x}}$

I need help on this it is a fraction subtract another fraction which is negative thx to whoever helps 5/7-(-1/7)

Sav [38]

Answer:

$\frac{5}{7}-(-\frac{1}{7})=\frac{6}{7}$

Step-by-step explanation:

To evaluate :

$\frac{5}{7}-(-\frac{1}{7})$

Solution:

Two negatives multiply to become a positive.

Thus, we can remove parenthesis by reversing the signs of the fraction by multiplying the negative outside.

⇒ $\frac{5}{7}+\frac{1}{7}$

Since the denominators are same for both fractions, so we simply add the numerators.

⇒ $\frac{5+1}{7}$

⇒ $\frac{6}{7}$ (Answer)
