In this section we are going to see how knowledge of some fairly simple graphs can help us graph some more complicated graphs. Collectively the methods we’re going to be looking at in this section are called transformations.
Vertical Shifts
The first transformation we’ll look at is a vertical shift.
Given:
The equation is
To find:
The value of b.
Solution:
We have,
Subtracting both sides by , we get
Therefore, the value of b is .
Answer:
Maya's hair grows at the rate of 1.25cm per month
Step-by-step explanation:
After Maya shaved her hair,
She monitored the growth and recorded the length of the hair monthly in centimeters using the equation ell=1.25mℓ=1.25mell
Therefore, since the length of hair is recorded on a monthly basis, 1.25 in the equation refers to the rate of growth as measured by the length of hair per month.
Answer:
1107
Step-by-step explanation:
72+ (33+12)23
= 72 + (45)23
=72+ 1035
=1107
