Is x=1 part of the domain of f(x)=the square root of x-10? Explain why/why not.

X = 1 is not part of the domain.

The solution to f(x) = √(x -10) is:

Domain: x ≥ 10, [10, ∞)
Range: f(x) = ≥ 0, [0, ∞)

The reason why x = 1 is not part of the domain because if you plug in the value of x into the function, it will result in √-9, which results in 3i. That’s why x = 1 is not part of the domain.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
