Answer 1

No slope. It's a parabola, which doesn't have slope.

Answer 2

Take derivative:
f'(4) = ....?

Answer 3

@quyenthuy820 Can you cooperate for your own good?

Answer 4

derivative of 4 is 0...

Answer 5

f(x) = 2x^2+x-3
->f'(x) = .....

Answer 6

f'(x)=4x+1

Answer 7

Good :) x = 4,
-> f'(4) = ....

Answer 8

17..?

Answer 9

That calls slope :)
