Draw te graph of y = 2x^2 +1 for =3 equal to or less than X,
equal to or less than 3.
By drawing a tangent , find the gradient of the curve at the
point
B (2,9)
The answer's 8 but i got 6.6....
Draw the graph of y = x^3 for -2< or equal to x < or equal
2
by drawing a tangent, find gradient of curve at the point where
x = -1.
the answer's 3 . but i got 4 despite many tries. could someone
try drawing this out and see whether the answer scheme is
correct??
