Question

semester 1: unit 4 exam review
domain & range
domain: (square leq x leq square)
range: (square leq y leq square)

Explanation:

Step1: Identify domain (x-values)

The graph starts at $x=0$ and ends at $x=14$, so the domain is the set of all x-values between these two points.
Domain: $0 \leq x \leq 14$

Step2: Identify range (y-values)

The lowest y-value is $0$ (at the start/end) and the highest y-value is $80$ (the peak of the graph), so the range is the set of all y-values between these two points.
Range: $0 \leq y \leq 80$

Answer:

Domain: $\boldsymbol{0 \leq x \leq 14}$
Range: $\boldsymbol{0 \leq y \leq 80}$
