Solution by Steps
step 1
To find the slope of the tangent line to the curve y=3x22x+1 y = 3x^2 - 2x + 1 at x=1 x = 1 , we need to compute the derivative of y y with respect to x x
step 2
The derivative of y y with respect to x x is dydx=6x2 \frac{dy}{dx} = 6x - 2
step 3
Evaluate the derivative at x=1 x = 1 to find the slope of the tangent line at that point: dydxx=1=6(1)2 \frac{dy}{dx} \bigg|_{x=1} = 6(1) - 2
step 4
Simplifying gives us the slope: 62=4 6 - 2 = 4
Answer
The slope of the tangent to the curve at x=1 x = 1 is 4.
Key Concept
