Answer:

Step-by-step explanation:
GIVEN: The weight, in pounds, of a newborn baby
months after birth can be modeled by the function
.
TO FIND: What is the y-intercept of the function and what is its interpretation in the context of the problem.
SOLUTION:
in 
if 

Hence y-intercept is 
the y-intercept in this represents the weight of baby just after he is born.
Answer:
X=-22
Step-by-step explanation:
Hello from MrBillDoesMath!
Answer:
For y = 4x, the domain of the function is all real numbers. This can be indicated as ( -infinity, infinity),
...later part of question:...
..."because an exponent can be any real"
exponent? !!!
Did you mean y = 4^x ? In this case the domain of y is all real numbers ann the range is (0, infinity), where the value 0 is not included in the range.
Thank you,
MrB
Answer:
This is the equation of a line with slope of 1 and the intercept point wit the 'y' axis is (0, 1.5)
Step-by-step explanation:
Lines have the following equation: y=mx+b, where 'm' is the slope and b is the interception with 'y' axis when 'x'=0
The attached pictures shows the equation of the line in a graph
