Chapter P Graphing Functions

  1. Hi Emily Logarithm! Love your presentation and transitions! (: However, the examples for odd and even functions can be more improved. For odd functions, it can be....

    '' Determine if the function is negative f(x)=2x^3-6x''.

    Let's solve it with the algebraic method of plugging in "-x".
    f(-x)= 2(-x)^3-6(-x)
    = -2x^3+6x
    = -(2x^3-6x)
    = -f(x)

    Therefore, f(x) is an odd function.

    For even functions, it can be.......

    ''Determine if the function is even f(x)= x^2-4''.

    Use the algebraic method by plugging in "-x" into the function.
    f(-x)= (-x)^2-4
    f(-x) x^2-4
    f(-x)= f(x)

    Therefore, we can conclude that f(x) is an even function.

    Thank you.
