2)Use point by point plotting to sketch the graph of the equation y=x-3
3)The equation below specifies a function. Determine whether the function is linear, constant or neither 9x+8y=5
4)use point by point plotting to sketch the graph of the function f(x)=3-x_3 (x with exponent 3)
5)Find the expression if f(x)=x_2+7x f(-3)
6)Determine if the equation specifies a function with independent variable x. if it does, find the domain. if it doesn't, find a value of x to which there corresponds more than one value of y 2x=y_2=10
7) Complete the square and find the vertex form of the quadratic equation f(x)=x_2-8x+69
