Sketch the graph of each linear equation. Be sure to find and show the \(x\) - and \(y\) -intercepts. $$ y=3 x-4 $$

Determine whether the graph of each function is symmetric about the y-axis or the origin. Indicate whether the function is even, odd, or neither. $$ f(x)=1+\frac{1}{x^{2}} $$

Solve each problem Write the area \(A\) of a square with a side of length \(s\) as a function of its diagonal \(d\).

Determine whether the graph of each function is symmetric about the y-axis or the origin. Indicate whether the function is even, odd, or neither. $$ f(x)=\sqrt{9-x^{2}} $$

Solve each problem Write the perimeter of a square \(P\) as a function of the area \(A\).

Sketch the graph of each linear equation. Be sure to find and show the \(x\) - and \(y\) -intercepts. $$ y=5 x-5 $$

Solve each problem. Withholding A student sells ice cream bars. Her weekly salary is given by \(S(x)=0.40 x+200,\) where \(x\) is the number of ice cream bars sold. Her employer determines the amount withheld for taxes using the function \(W(x)=0.20 x\), where \(x\) is her weekly salary. Write the amount withheld as a function of the number of ice cream bars sold. Use composition.
