Question

2x2 +1 passing through the points (1,3) and (1.1 ,3.57). Round your answer to one decimal places. Find the slope of the secant line for the function fx) Answer: 65.98 Question 2 0/ 25 points Find the slope of the secant line for the function f(x)=3.1x2-2.0x passing through the points where x=1 and x-0.7. Round your answer to two decimal places. Answer: 0.32 Question 3 0/ 25 points Approximate the slope of the line tangent to f(x)=2x2 at -4. Be sure to use an increment that is small enough for the answer to be accurate to two decimal places. Answer: 1.42 Question 4 25 / 25 points The point P(1,1) lies on the curve f(x)-x*. Let Q(xoxo be an arbitrary point on the curve, and let s be the secant line drawn through P and Q. Let the slope of the secant line drawn through P and Q be denoted by ms Find Iin ms secant line drawn through P and Qbe denoted by ms. Find Iim,m. -3 4 4

Explanation / Answer

1) Solution

m = (y2-y1)/(x2-x1) = (3.57-3)/(1.1-1) = 5.7
slope = 5.7
