Quadratic inverse for y=x^2-1

1 answer:

8 0

let's recall that to find the inverse of any expression, we start off by doing a quick switcheroo on the variables, and then solve for "y".

$\bf y = x^2-1\implies \stackrel{switcheroo}{x=y^2-1}\implies x+1=y^2\implies \sqrt{x+1}=\stackrel{f^{-1}(x)}{y}$

Answer:

recursive:

a(1)=7 a(n)=a(n-1)-3

explicit:

a(n)=7-3(n-1)

Step-by-step explanation:

for recursive you use a(n)=a(n-1) and then whatever the sequence is. Since yours goes down by 3, it would be -3 at the end.

For explicit, you use a(n)= first number in sequence+the difference in the sequence(n-1)

$2.50(f) + $4(n) = Total Cost

$2.50(9) + $4(9) = Total Cost

$22.50 + $36 = Total Cost

$58.50 = Total Cost
