Question

If the tangent line to y=f(x) at (1, -6) passes through the point (-1, 2), find :
A.f(1)=
B.f'(1)=

Answer 1

you are given \(f(1)\) in the problem. you are told that \((1,-6)\) is on the graph, making \(f(1)=-6\)

Answer 2

as for \(f'(1)\) it is the slope of the tangent line, so your second job is to find the slope of the line between the points \((1,-6)\) and \((-1,2)\)

Answer 3

right two, down eight, slope is minus four
