Identify the equation for the graph shown below \[ \begin{array}{l} y=-x^{2}+3 \\ y=x^{2}-3 \\ y=x^{2}+3 \\ y=-x^{2}-3 \\ y=x+3 \\ y=x-3 \end{array} \] Write an equation for a line parallel to \( y=5 x-4 \) and passing through the point \( (4,19) \) Find the domain of the function in interval notation: \( f(x)=\frac{1}{x+1} \) During a football game the parents of the Devils football players sell nachos and popcorn to raise money for new uniforms. They charge \( \$ 5.50 \) for nachos, and \( \$ 3.50 \) for a bag of popcorn. The parents collect \( \$ 678.00 \) in sales during the game. They sell a total of 156 items. Set up a system of equations and solve to determine how many nachos and bags of popcorn were sold. Number of nachos sold: Number of bags of popcorn:
