Determine the domain Of the function. z = √1-x² - y².

Graph f(x)=x22x+3 by using its properties.

Find the domain of the function, g(x)=5x43. Write the domain in interval notation.=

An outpatient operating room charges each patient a fixed amount per surgery plus an amount per minute for use. One patient was charged 250 for a 30-minute surgery and another patient was charged 450 for a 90-minute surgery. Determine the linear function that would be used to compute the charges. Use the function to determine the charge when a patient has a 45-minute surgery.
