Question
The instantaneous slope of f(x)
when f(x) is radical
10
A-1:8qrt(13)
4,0
f(x) = √4x + 5
compute the instantaneous slope at: (-1, √I)
Start with two points
A: (-1, VI) and B: (−1+h, ?)
What is the y-coordinate of B?
• Because the a-coordinate of B depends on h, the y-coordinate will also depend on h.
