Give the domain of the following functions. Give your answer in interval notation. a) f(x)= 5x-2/x^2-5x+6 and b) square root of 5-2x

  • Math -

    a) f(x) = (5x-2)/((x-2)(x-3)) , the brackets are essential.

    domain: any real number , except x=2, x=3

    b) f(x) = √(5-2x)
    we can't take the square root of a negative, so
    5-2x ≥ 0
    -2x ≥ -5
    x ≤ 5/2
