    domain is the set of x values you can put into the function so since it starts at -2 on the x axis and continues infinitely onwards domain: x>-2

    to see if a quadratic has any solutions you will have to use the formula for the descriminant b²-4ac 3=a 5=b 10=c sub them in if x <0 no real solutions x=0 1solution x>0 2 solutions
