Question 886663
Consider f(x) = 2x + 3. Find the inverse of this function. Verbally, compare what f does to x (“multiply by 2, then add 3”) to what f^-1 does to x.
<pre>
f(x) = 2x + 3
y = 2x + 3
x = 2y + 3 ---- Interchanging x and y
2y = x - 3
{{{y = (x - 3)/2}}}
{{{highlight_green(highlight_green(f^-1(x) = (x - 3)/2))}}}
You should be able to do the comparison!!
