If f(x)=6x-4 , what is f(x) when x=8?

Break Down the Problem

1. Identify the function: $f(x) = 6x - 4$
2. Substitute the value of $x$ into the function: $x = 8$

Relevant Concepts

1. We need to evaluate the function $f(x)$ using the given value of $x$.

Analysis and Detail

1. Substitute $x = 8$ into the function: $f(8) = 6(8) - 4$

Carry out the calculations

1. Calculate $6 \times 8$: $6 \times 8 = 48$
2. Now subtract 4: $48 - 4 = 44$

Verify and Summarize

1. Confirm the calculations:
   • $6 \times 8 = 48$
   • $48 - 4 = 44$

Final Answer

$f(8) = 44$
