13. Antler Problem: Based on data collected on mule deer in Colorado, the mass of a deer’s antlers
(measured in October) varies linearly with the deer’s age. According to the data, a 30 month old deer’s
antlers are about 152 grams and an 80 month old deer’s antlers are about 552 grams. (Assume most deer
don’t live past 20 years).
 Write a particular equation expressing antler mass in terms of the deer’s age.

Predict the antler mass of a 51 month old mule deer.

Suppose that you brought back a mule deer whose antlers are 432 grams. About how old was he?

What is the age-intercept? What does this number tell you about the problem?

What is the antlers mass-intercept? What does this number tell you about the problem?

What are the units of the slope? What does this number tell you about the problem?

Sketch the graph of this function using a suitable domain and range.

What is the domain and range of this function?
If f ( x)  x 2  4 x  7 , g ( x)  8  3x and h( x)  5x  2 evaluate the following.
14. f (2)
15. h( f (3))
16. g (4)  h(4)
17. 3 f (3)  2 g (5)
18. g (h( x))
19. ( f
g )(4)
Identify whether the graph is a function and find the domain and range for each graph.
