Given that g (x) = x^2 , find each of the following.

a) g (1)

b) g (-2)

c) g (-x)

d) g (2y)

e) g (2+h)

G (x) = x²

a) To find g (1) substitute with x = 1 at the function g (x)

∴ g (1) = 1² = 1

b) substitute with x = - 2 at the function g (x)

∴ g (-2) = (-2) ² = 4

c) substitute with x = - x at the function g (x)

∴ g (-x) = (-x) ² = x²

d) substitute with x = 2y at the function g (x)

∴ g (2y) = (2y) ² = 4y²

e) substitute with x = 2+h at the function g (x)

∴ g (2+h) = (2+h) ² = h² + 4h + 4
