Question

Write the function whose graph is the graph of y=x³ +3, but is reflected about the y-axis.

Answer 1

Reflected function is y = - x³ + 3

Explanation:

When a function f(x) is reflected about the y-axis, the reflected function becomes g(x) = f(-x)

f(x) = x³ + 3

f(-x) = (-x)³ + 3 =-x³ + 3
