The t-axis represents the time that it takes for the cycles to occur. Because the question asks for two cycles, the domain of the graph is {t|0 ≤ t ≤ 0.04, t ∈ R}. The range represents the volts at any given time. The range of the graph is {y|−170 ≤ y ≤ 170, y ∈ R}.
- The period is 0.02 s.
- The voltage will reach 110 V twice every 0.02 s (or every cycle). In 1 s, this means that there will be 50 cycles; therefore, the voltage will reach 110 V 100 times in 1 s.
