For #4, the derivative is a quadratic. There are 2 places where the tan line has a slope of 5. Find the points where it equals 5 (or where that minus 5 equals zero) and then you have 2 points and 2 slopes

For quadratic equation i would need a,b and c. but i have only 2 numbers......and how would i find the point where the point equals 5?
Also can anyone check the solutions i did,
thanks
