What happens to the value of the expression 1+3f as f increases? Choose 1 answer: A It increases. (B) It decreases. (C) It stays the same.

Analysis of the expression: Let's analyze the expression 1+3f. As f increases, we multiply this increase by 3 (since f is multiplied by 3 in the expression). This means that the whole expression 1+3f will increase by three times whatever amount f increases.Increase in expression with increasing f: To check this, let's pick two values for f, where the second value is greater than the first. For example, let f1 = 1 and f2 = 2. When f = f1, the expression 1+3f becomes 1+3(1) = 1+3 = 4. When f = f2, the expression 1+3f becomes 1+3(2) = 1+6 = 7. We can see that as f increased from 1 to 2, the value of the expression increased from 4 to 7.Checking with specific values of f: Since the expression increases whenever f increases, we can conclude that the value of the expression 1+3f increases as f increases. Therefore, the correct answer is A) It increases.

Analysis of the expression: Let's analyze the expression $1+3f$ . $\newline$ As $f$ increases, we multiply this increase by $3$ (since $f$ is multiplied by $3$ in the expression). $\newline$ This means that the whole expression $1+3f$ will increase by three times whatever amount $f$ increases.
Increase in expression with increasing $f$ : To check this, let's pick two values for $f$ , where the second value is greater than the first. $\newline$ For example, let $f_1 = 1$ and $f_2 = 2$ . $\newline$ When $f = f_1$ , the expression $1+3f$ becomes $1+3(1) = 1+3 = 4$ . $\newline$ When $f = f_2$ , the expression $1+3f$ becomes $1+3(2) = 1+6 = 7$ . $\newline$ We can see that as $f$ increased from $f$ $1$ to $f$ $2$ , the value of the expression increased from $f$ $3$ to $f$ $4$ .
Checking with specific values of $f$ : Since the expression increases whenever $f$ increases, we can conclude that the value of the expression $1+3f$ increases as $f$ increases. $\newline$ Therefore, the correct answer is A) It increases.
