Question

HELP! Find the domain and range of a function

Answer 1

plug in one of the numbers from the domain list in for x to solve for f(x) to see if the equation is true

Answer 2

Going from top to bottom

f(x)=4-4x; f(x)=5x-3; f(x)=-10x; f9x0=3/x+1.5

Just plug in zero where x is and find the range that has that number.
