Question 261306
How do I Graph the function f(x) = x + 2?

treat f(x) which means y is a function of x as y
a function is when for every value of x there exists only one y
f(x) = x + 2 is the equation of a line
a line is y=mx+b where m is the slope and b is the y-intercept (or vertical intercept at (0,b))
in this case m=1 and b=2
to graph means you plug in values for the function and plot them on a coordinate grid


{{{ graph( 300, 200, -5, 5, -5, 5, x+2) }}}
