Question

Determine the slope of the secant line for the curve defined by the equation:
f(x)=-7x^2 + 3 for the points determined by x(sub0)=7 and x(sub1)=10.

Answer 1

at x(sub0)=7 f'(x(sub0))=-7*2*0=0
at x(sub1)=10 f'(x(sub1))=-7*2*1=-14

Answer 2

for the first on it's -7*2*7=-14*7=-98
and the second it's -7*2*10=-140

Answer 3
