Easy Quantitative Comparisons Functions

Consider the function defined by $$f(x) = 2x + 3$$.

Evaluate the following expressions for $$x = 4$$:

1. $$f(x)$$

2. $$f(2x)$$

Which of the following options describes the relationship between the values of these two expressions?

$$f(x) < f(2x)$$

$$f(x) = f(2x)$$

$$f(x) > f(2x)$$

$$f(x) ext{ is not comparable to } f(2x)$$
