There is no difference, both equal 40.
Answer:
(f • g)(3) = 100, the distance in miles the bus traveled
Step-by-step explanation:
The product of (miles/hour) and (hours) is (miles), so only answers with units of distance are applicable. The numbers are ...
f(3) = 2·3² +2 = 20 . . . . miles per hour
g(3) = 3+2 = 5 . . . . hours
so (f·g)(3) = f(3)·g(3) = 20·5 = 100 . . . . miles
This means only the first answer choice is applicable.
The generic form for this case is given by
y = m (x-xo) + yo
where
xo: x coordinate
me: y coordinate
Substituting the values we have
y = 5 (x-3) - 4
Therefore, the answer in this case is
y – (–4) = 5(x – 3)
|f(a)| , the vertical lines mean absolute value. Absolute value is the positive value of the answer whether it is actually negative or positive.
F(a) is given as -5, so the absolute answer would be 5
The answer is 5
