Answer:
(x - 12)²/9
Step-by-step explanation:
y = 3sqr(x) + 12
Make x the subject:
y - 12 = 3sqrt(x)
(y - 12)/3 = sqrt(x)
Square both sides
(y - 12)²/9 = x
Interswitch variables
inverse function is:
(x - 12)²/9
If f(x) = (x + 12)^⅓
Then,
y = (x + 12)⅓
y³ = x + 12
y³ - 12 = x
f inverse:
x³ - 12
Answer:
538
Step-by-step explanation:
if you round the hundreth place up, the tenth place would be 1. However, rounding that would give you 0 as it's less than 5. Therefore, all decimal places would become 0, and that only leaves 538.
It works out that: y = 1 or 5 and therefore x = 5 or 1
