we have the function

Remember that
The Amplitude is the height from the center line to the peak (or to the trough). Or we can measure the height from highest to lowest points and divide that by 2
In the general form of the equation of the sine

The amplitude is the factor A
so
In this problem
The amplitude is 1/2
using a graphing tool
Note that the amplitude is the height from the center line to the peak (the center line is the x-axis, so the distance is 0.5.
Answer:
3 units right
Step-by-step explanation:
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then shift left of a units
• If a < 0 then shift right of a units
Thus f(x) → f(x - 3) represents a shift of 3 units to the right
Answer:
2.0
Step-by-step explanation:
x = age
y = average systolic blood pressure
x₁ = 40 years old, y₁ = 110 systolic blood pressure
x₂ = 50 years old, y₂ = 130 systolic blood pressure

∴ Slope of the regression line is 2.0
