Question

Can you show me the graph for f(x) = 1/2 x + 2

Answer 1

It's a linear function y = mx + b.

The graph is a straight line.

We need only two points to plotting a graph of linear function.

Choose two values of x and calculate values of y.

$f(x)=\dfrac{1}{2}x+2\to y=\dfrac{1}{2}x+2\\\\for\ x=0\to y=\dfrac{1}{2}(0)+2=0+2=2\to(0,\ 2)\\\\for\ x=-4\to y=\dfrac{1}{2}(-4)+2=-2+2=0\to(-4,\ 0)$

Answer 2

Here is the graph with your line in it.
