The second question is (x-5)(2x+7)
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 =
How is this college? None the less, the answer is D as it shows an included domain of all numbers less than three and due to the filled in circle, we can conclude that 3 itself is also included.
