Blood pressure can be modeled by a sinusoidal curve, where the maximum and minimum on the curve correlate to the person’s blood pressure reading. Henry’s blood pressure is modeled by the function , where t is time in seconds.Which graph accurately depicts this model?
Answer
A
On a coordinate plane, seconds is on the x-axis and blood pressure is on the y-axis. A curve starts at (0, 100). It has a maximum of y = 130 and a minimum of y = 70. It goes through one cycle in 1 second.
B
On a coordinate plane, seconds is on the x-axis and blood pressure is on the y-axis. A curve starts at (0, 100). It has a maximum of y = 130 and a minimum of y = 70. It goes through one cycle in 2 seconds.
C
On a coordinate plane, seconds is on the x-axis and blood pressure is on the y-axis. A curve starts at (0, 0). It has a maximum of y = 30 and a minimum of y = negative 30. It goes through one cycle in 1 second.
D
On a coordinate plane, seconds is on the x-axis and blood pressure is on the y-axis. A curve starts at (0, 30). It has a maximum of y = 60 and a minimum of y = negative 0. It goes through one cycle in 1 second.
