Inverting a function is equivalent to solve the equation x = f(y) for the variable y.
Take the function:
y = ∛(x – 2) + 6
Switch x and y, and then solve the equation for y:
x = ∛(y – 2) + 6
x – 6 = ∛(y – 2)
∛(y – 2) = x – 6
Cube both sides:
[ ∛(y – 2) ]³ = (x – 6)³
y – 2 = (x – 6)³
y = (x – 6)³ + 2 <——— and there it is, the inverse function.
I hope this helps. =)
Answer:
1363.6
Step-by-step explanation:
let the basic salary be = x
10% of x = 10/100x
So the equation = x + 10/100x = 1500
= x + 0.1x = 1500
= 1.1x = 1500
= x = 1500/1.1
= x = <u>1363.6</u>
Answer:
D) c - 2 = 25 + c + 10√c
Step-by-step explanation:
The given equation is
Taking square on both sides, we get
Here we used ( a+ b)^2 = a^2 + b^2 + 2ab formula.
c - 2 = 5^2 + (√c)^2 + 2(5)√c
c - 2 = 25 + c +10√c
Answer: D) c - 2 = 25 + c + 10√c
Thank you.
