Replace the variable x with -4 in the expression.
f (- 4) = 3(- 4)^2 - (- 4) + 23
Simplify each term.
f (- 4) = 48 + 4 + 23
Simplify by adding numbers.
f (- 4) = 75
The final answer is 75.
Answer:
the minimum is 410, the max is 450
Step-by-step explanation:
to find the minimum you would do 430-20 and the max would be 430+20
The domain is just the x values.
Domain: -8,4,5,7
Equations:
1. (30)(5)= 150
2. 30 + 30 + 30 + 30 + 30 = 150
I round:
30 dollars divided by 5 rounds = 6 dollars per round.
