Answer:
W(t) = 10 + 1.5*t
Step-by-step explanation:
Given:
The weight gain of the baby is 1.5 pounds per month.
After 4 months, baby's weight = 16 pounds
Let us the say the weight of the baby when it was born be x.
Then:
x + 1.5*(4) = 16
x = 10
Then weight of the baby as a function of number of months(t) will be=
initial weight + incremental weight per month*no of months(t).
W(t) = 10 + 1.5*t
Answer:
-The slope:

Step-by-step explanation:
-To find the slope, you need this trick:

-So, according to the graph, start to the first doted point which is (0,1) to get to the second doted point, which is (2,4) on the graph, by counting how far up and how far across:
Rise: 3
Run: 2

So, therefore the slope is
.
Y=3x^2. -12x+6
If x= 0 then y= 3•0^2 -12•0+6=6
X=0, y=6
y intercept is the place where the curve touches the y-axis and is at point (0, 6)
