1. Notasi faktorial: a. \( n!=n \cdot(n-1) \cdot(n-2) \cdot \ldots \cdot 3 \cdot 2 \cdot 1 \), untuk \( n \) bilangan bulat positif, b. \( 0!=1 \)

A pre-paid cell phone company charges \( \$ 10.05 \) as a monthly access fee and \( \$ 0.11 \) per minute of calling time. Express the monthly cost \( C \) in terms of minutes of call time.

Consider \( g(x)=5 x-12 \). For what interval(s) is \( g(x) \) positive? negative? positive: \( \left(\frac{12}{5}, \infty\right) \); negative: \( \left(-\infty, \frac{12}{5}\right) \) o positive: \( (-\infty,-12) \); negative: \( (-12, \infty) \) positive: \( (-12, \infty) \); negative: \( (\infty,-12) \) positive: \( \left(-\infty, \frac{5}{12}\right) \); negative: \( \left(\frac{5}{12}, \infty\right) \)

\( f(x)=3 x+2 \) and \( g(x)=6 x+4 \)

On page 87 , Ben says to himself, "Did Achilles get caught napping inside the Trojan horse?" What type of figurative language is this and why do you think the author chose to use it to compare what Ben and Griffin are doing to the Trojan war? Explain your thoughts.

The graph of \( f(x)=(x-3)^{2} \) is exactly the same as the graph of \( f(x)=x^{2} \), except the graph of \( f(x)=(x-3)^{2} \) is shifted a down 3 units. o of dight 3 units.
