Question

the function $f$ is defined by $f(x)=155x - 30$. what is the value of $f(x)$ when $x = 6$?

Explanation:

Step1: Substitute x value

Substitute $x = 6$ into $f(x)=155x - 30$.
$f(6)=155\times6 - 30$

Step2: Calculate multiplication

Calculate $155\times6$.
$155\times6 = 930$
So $f(6)=930 - 30$

Step3: Calculate subtraction

$930-30=900$

Answer:

900
