if a problem requires you to determine the value of the independent variable, x, for a given value of the dependent variable, f(x), then substitute the number in for
a) a
b) f(x)
c) x
d) the vertex

Explanation:

To solve this, we analyze the context of finding \( x \) (independent variable) for a given \( f(x) \) (dependent variable). When we know \( f(x) = \text{some value} \), we substitute that value into \( f(x) \) to solve for \( x \). For example, if \( f(x)=2x + 1 \) and we know \( f(x)=5 \), we substitute \( 5 \) for \( f(x) \) to get \( 5 = 2x+1 \) and then solve for \( x \). So the correct option is the one where we substitute the number for \( f(x) \).

Answer:

b) \( f(x) \)
