Answer:
The constant term in the function is 5
Step-by-step explanation:
we have
where
b is the y-intercept or the constant term of the function
Remember that
The x-intercept is the value of x when the value of the function is equal to zero
so
For x=-3 ----> f(x)=0
For x=-5 ----> f(x)=0
substitute any of the intercepts in the function
For x=-3
Verify with the other intercept
For x=-5
---> is true
therefore
The constant term in the function is 5
Answer:
It descends 3 km.
Step-by-step explanation:
The rate of change is the slope. The formula for slope is
Using the first two points, (0, 12) and (2, 10), we have
m = (10-12)/(2-0) = -2/2 = -1
This means the plane descends 1 km per minute. This means in 3 minutes' time, the plane descends 3 km.
