Answer:
In year 1986 the average cost of car is $12,000
Step-by-step explanation:
Cost function:
C = 30.5t² + 4192
Cost = $12,000
Find:
Year
Computation:
C = 30.5t² + 4192
12,000 = 30.5t² + 4192
t = 16 year
So,
Year 1970 + 16 year
1986
So, In year 1986 the average cost of car is $12,000
Answer:
Via its graph, you can identify exponential and linear functions. Linear functions are straight lines, while curved lines are exponential functions. By the adjustment in y, you can also recognize them. If you apply the same number to y, then the function changes continuously and is linear.
Step-by-step explanation:
Answer:
take the number (x,y) take Y subtract 2.. take x add 5. if the origin is 0,0 it would end 5,-2. if Q is 7,3
7+5 = 12
-3-2 = -5
answer (12,-5)

Answer:
f(3) = 9
Step-by-step explanation:
f(x) = x^2
f(3) means "When x is 3" So, we substitute x with 3.
f(3) = 3^2
f(3) = 3 x 3 = 9
f(3) = 9
