Comparing Function Values

Easy Quantitative Comparisons Functions

Consider the following function defined for all real numbers:

$$ f(x) = 2x + 3 $$

Evaluate the expressions $$ f(2) $$ and $$ f(4) $$, and determine which expression is larger:

Is $$ f(2) $$ greater than, less than, or equal to $$ f(4) $$?

$$ f(2) < f(4) $$

$$ f(2) > f(4) $$

$$ f(2) = f(4) $$

$$ f(2) \text{ is not defined for real numbers} $$
