\(f(x)=2(x+1)\); Find \(f(2)\)

\(f(2)=2(2+1)\)

\(f(2)=2(3)\)

\(f(2)=6\)

\(1+1\)

\(2\)

To find the inverse of a function switch x and y and then solve for y

Example:  \(y=3x+2\)

Switch x and y

\(x=3y+2\)

subtract 2 from both sides

\(x-2=3y\)

divide 3 from both sides

\((x-2)/3=y\)

rewrie with y on the left

\(y=(x-2)/3\)

The inverse of \(y=3x+2\) is \(y=(x-2)/3\)

\(-2x+3y-6\); \(x=3\), \(y=-2\)

\(-2*3+3*(-2)-6\)

\(-6+3*(-2)-6\)

\(-6+-6-6\)

\(-6-6-6\)

\(-12-6\)

\(-18\)

\(-3x+-6--8-6\)

\(-3x-6--8-6\)

\(-3x-14-6\)

\(-3x-20\)

Let b = number of miles Jillian bikes in the evening for one day; Let m = total number of miles; Let d = number of total days; Let r = number of miles Jillian runs in the morning for one day

\(b=(m-dr)/d\)

\(b=(30-3*5)/5\)

\(b=(30-15)/5\)

\(b=15/5\)

\(b=3\)

Jillian bikes for a total of 3 miles each evening

\(tan(126° +43')\)

\(tan(126° + 0.7166666666666667°)\)

\(tan(126.7166666666666667°)\)

\(sin(126.7166666666666667°)/cos(126.7166666666666667°)\)

\(0.801601768216/cos(126.7166666666666667°)\)

\(0.801601768216/-0.597858348769\)
