Consider the function f(x)=x2+5x+5 and the point A(4,5).
Find a formula for the slope of a line passing through point A, and an arbitrary point on the function. Your answer should be a formula in terms of x.
The Attempt at a Solution
Using your answers from the two previous questions, find the slope(s) of the line(s) through point A that is (are) tangent to f(x)
the slopes are 1, and 25 however I don't understand what part two of the question is asking for...
