How I write h(x)=x2-1 in a functions equation?

Explain how to find the inverse of a function from its equation. Use an example to demonstrate the steps.

The half-life of plutonium-244 is 80,000,000 years. Find function gives the amount of carbon-14 remaining as a function of time, measured in years.

How do you find the inverse of a function algebraically?

Why does the domain differ for different functions?

How do you determine if an equation in x and y defines y as a function of x?

solve for y to determine if y is a function of x. If it is, express it using function notation. What is the domain?  x+y^2=2

find the equation of the inverse of one-to-one function n(y) - y^2+9, y≥ 0

A helicopter takes off from the roof of a building that is 175 feet above the ground. The altitude of the helicopter increases by 150 feet each minute. (a) Use a formula to express the altitude of a helicopter as a function of time. (Let t be the time in minutes since takeoff and A the altitude in feet.) A = 175 + 150t (b) Express using functional notation the altitude of the helicopter 210 seconds after takeoff. A(2.5 x ) Calculate that value. (Round your answer to the nearest foot.) ft

Do you use x-coordinates or y-coordinates when describing where functions increase, decrease, or are constant?
