Write an equation to construct a function whose graph is like that of y=x^2, except for pieces removed for values between 3 and 5, and 8 and 9.

I am not sure how to approach this question. Would I make a piece wise function? PLease helpp brains about to explode!

  • PreCalculus -

    Wouldn't you just include the following domain for x,
    x ≤ 3 OR 5≤x≤8 OR x ≥ 9 ?

    something like

    f(x) = x^2, x ≤ 3 OR 5≤x≤8 OR x ≥ 9

    You don't say what happens to the function for the restricted values of x, so it would be just a discontinuous function I suppose.

    how would this equation look: y=f(x+3) when y=f(x)= x^2 would it look like so.... x^2(x+3) adam, there's a slight problem with your notation in the expression y = f(x+3). Ordinarily we wouldn't put an expression in place of a variable, …
