even/odd: A function f is even if the graph of f is symmetric with respect to the y-axis. Algebraically, f is even if and only if f(-x) = f(x) for all x in the domain of f. A function f is odd if the graph of f is symmetric with respect to the origin. Algebraically, f is odd if and only if f(-x) = -f(x) for all x in the domain of f. solve algebra: [MATH](scroll to solver) enter the equation so one part is zero: x-6x^(1/2)+4=-5 add 5 x-6x^(1/2)+9=0 enter that into the calculator press [ENTER] press [ALPHA][ENTER] bam fraction <-> decimal: [MATH][1]: convert answer to fraction [MATH][2]: convert answer to decimal
