What is the rate of change
2 answers:
Answer:
A rate of change is a rate that describes how one quantity changes in relation to another quantity. If x is the independent variable and y is the dependent variable
You can find the rate of change by using this formula:
That m would go into another formula known as slope-intercept form
The equation is
y = mx +b
m = rate of change (or) slope
b = y-int

Step-by-step explanation:
Explaining the sine function:
The sine function is defined by:
In which A is the amplitude, is the period,
is the horizontal shift and V is the vertical shift.
So, in your problem:
The amplitude is 4, so A = 4.
The period is , so
.
There is no horizontal shift, so .
The vertical shift is −3, so V = -3.
The sine function that represents these following conditions is
