Graph f(x)=1/2x+2. use the line tool and select two points to graph the line.

If the graphs of the linear equations in a system are parallel, what does that mean about the possible solution(s) of the system? a. there are infinitely many solutions. b. there is no solution. c. there is exactly one solution. d. the lines in a system cannot be parallel.

Marcus needs to rewrite f(x) = x2 + 6x + 4 in vertex form.

What is the value of f(x) = 2.2 for f(-2)?
