The strings cost $14. you would take the total cost ($72) and subtract the cost of the book ($16) and you would get $56. you would then divide 56 by the number of book bought (4 in all) and you would get $14.
Answer:
answer D. $1.96
Step-by-step explanation:
Answer:
The initial value of the function is <u>2</u>
The base of the function is <u>3</u>
The function shows exponential <u>growth</u>
Step-by-step explanation:
f(x) = 2(3^x)
Exponential functions are those with the following equation:
y = a*b^x
where a ≠ 0, b > 0 and b ≠ 1 and x is a real number.
<em>a</em> is the y-intercept and <em>b </em>is the base.
The initial value of the function is the same as the y-intercept
If <em>a</em> is positive, the function growth. If <em>a</em> is negative, the function decay
