Practice problem
Given functions q(x)=1xq(x)=\dfrac1{\sqrt x}q(x)=x1 and h(x)=x2−9h(x)=x^2-9h(x)=x2−9, what is the domain of q(x)h(x) \dfrac{q(x)}{h(x)}\:h(x)q(x)?
{x∣−∞<x<∞,x≠3∪x≠−3}\{x|-\infty<x<\infty,x\neq3\cup x\neq-3\}{x∣−∞<x<∞,x=3∪x=−3}
x≥0x\geq0x≥0
−∞<x<∞-\infty<x<\infty−∞<x<∞
{x∣x>0,x≠3}\{x|x>0,x\neq3\}{x∣x>0,x=3}
Type a concept, like “slope” or “photosynthesis”.
