1. Evaluate the function rule for the given value.
f(x) = 3x for x = -5

15

Step-by-step explanation:

just 3 time 5 15 is  and anytime you have a number by a variable it just means multiple

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
