Question

Not sure how to do this problem, domain of a function...See attached

Answer 1

ok... so the domain of a function is the values of x, you can input into the equation.

you should know you can't take the square root of a negative number

so that means

\[9x - 10 \ge 0\]

if you solve for x, you will get the domain of the function.

an alternate method is to use some graphing software like

graph the curve and look at the x values that can be input

hope it helps
