What is the inverse function f(x)=2x +1
Neko [114]

The inverse function is f(x) = \frac{x - 1}{2}


You can find the inverse of any function by switching the f(x) value and the x value. Then solve for the new f(x) value. The result will be your inverse function. Below is the step-by-step process for solving this one.


f(x) = 2x + 1 ---> Switch the f(x) and x values

x = 2f(x) + 1 ---> Subtract 1 from both sides

x - 1 = 2f(x) ----> Divide each side by 2.

\frac{x - 1}{2} = f(x) ---> Switch the order so that it looks like a function.

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


And that would be your inverse function.

Quan bought 8.6 meters of frabic. how many cm of fabric did he buy
stira [4]
When you convert from meters to centimeters, you always multiply by 100, which means that 1 meter = 1 * 100 cm = 100 cm
So, 8.6 meters = 8.6 * 100 cm = 860 cm 

Hope this Helps :)
