Answer:
Slope of a tangent to the curve =
Step-by-step explanation:
Given - y = 1/x+1
To find - Identify each expression that represents the slope of a tangent to the curve y=1/x+1 at any point (x,y) .
Proof -
We know that,
Slope of tangent line = f'(x) =
We have,
f(x) = y =
So,
f(x+h) =
Now,
Slope = f'(x)
And
∴ we get
Slope of a tangent to the curve =

Answer: -a (4th choice)
Explanation:
Consider an example like y = 2(x-3)^2 and compare it to y = -2(x-3)^2
The jump from a = 2 to a = -2 means we reflect over the x axis. This is because we're effectively multiplying the y coordinate values by -1. So a point like (5,8) moves to (5,-8).
