f(x) = x² + 2
y = x² + 2
x = y² + 2
x - 2 = y²
√(x - 2) = y
√(x - 2) = f⁻¹(x)

Answer as decimal: 0.8462
Y=x2-1 is not a linear equation only because for it to be an linear equation it would have to be 2x-1=y or y=2x-1
The median is 7.

Arrange data in numerical order
1 3 3 6 8 10 10 15
Total number are 8, N = 8
Take the middle two numbers 6 and 8 and take their average
6+8/2 = 14/2 = 7
Therefore the median is 7.
