Find the slope of tangent to the curve y = x2+x+1 at (1,2)

1.	Find the slope of tangent to the curve y = x2+x+1 at (1,2)
Answer» Answer : 3 Explanation: y = x² + x + 1 Slope at any point = dy/dx THEREFORE, dy/dx = 2x + 1 = 2× 1 + 1 = 3

Answer»

Answer :

Explanation:

y = x² + x + 1

Slope at any point = dy/dx

THEREFORE, dy/dx = 2x + 1

= 2× 1 + 1

= 3
