The weight, in pounds, of a newborn baby tt months after birth can be modeled by the function W(t)=1.25t+6.W(t)=1.25t+6. What is the yy-intercept of the function and what is its interpretation in the context of the problem?

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.

step-by-step explanation:

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
