Consider the functions g(x) = 5^x and f(x) = 3x^2 + 6. Which function has a greater value when x = 1? As x increases will this function always be greater? Explain.

• When x = 1, g(x) is greater. It will always be greater because it is exponential.

• When x = 1, f(x) is greater. It will not always be greater because g(x) is exponential.

• When x = 1, f(x) is greater. It will always be greater because it is quadratic.

• When x = 1, g(x) is greater. It will not always be greater because f(x) is quadratic.
