Answer:
Point (2, 20) does not lie on the given curve.
Step-by-step explanation:
Let us see explanation:
(2, 20) is not on the curve.
When x = 3, f(x) = 2*5^3 = 250 . So (3, 250) is on the curve.
When x = 1, f(x) = 2*5^1 = 10 . So (1, 10) is on the curve.
When x = 2, f(x) = 2*5^2 = 50 . So (2, 50) is on the curve.
From the last line we see that (2, 20) is NOT on the curve.
x=3
y=1/2

==> ac + b = d
==> ac = d - b
==> a = (d - b)/c
