Answer:
y = x² + 2
Step-by-step explanation:
Given
x =
( square both sides )
x² = y - 2 ( add 2 to both sides )
x² + 2 = y
Answer:
72 dal
Step-by-step explanation:
short form to dekaliter is dal
The average rate of change of function describes the average rate at which y-value ( or f(x)) is changing with respect to changing x-value.
The average rate of change=

In this exaple is x1=4 and x2=7 and we will find y1 and y2:
y1=3(4-3)²+4=3*1+4=7
y2=3(7-3)²+4=3*16+4=48+4=52
Finally:

Answer: The average rate of change for f(x) from x=4 to x=7 is 15.
Answers:
- Enlargement
- The new larger rectangle is 16.8 inches by 8.4 inches
==============================================================
Explanation:
I'm assuming 7/5 is the scale factor. If so, notice how 7/5 = 1.4 which is larger than 1.
The scale factor being larger than 1 means we have an enlargement.
The image is going to be larger compared to the preimage.
The preimage rectangle is 12 in by 6 in. Multiply each dimension by 1.4 to get 12*1.4 = 16.8 and 6*1.4 = 8.4
The image rectangle is 16.8 inches by 8.4 inches
