Here is the full $$\LaTeX$$ according to the order of operations:

1. Let $$f(x)= 3x+\frac{3}{x}+1$$. Find the domain of $$f$$

2. Let $$q(x)=\frac{2}{\sqrt{x}}$$. Find the domain of $$q$$

3.Let $$g(x)=3(x-6)^2+1$$. Find the range of $$g$$

4.let $$f(a,b)= 2a-3b^2+7$$. If $$f(k,3)=90$$, then what is k?

5.Define the operation$$\heartsuit$$ so that, $$a \heartsuit b=a+b/2$$

Find the value of $$(5 \heartsuit 7) \heartsuit 11-5 \heartsuit (7 \heartsuit 11)$$
