What are the important points needed to graph g(x)=x24x+4?

1 Answer

x=2
g(x)=4
Both at their x/y intersects

Explanation:

Let's just make g(x)=y so it's easier.

y=x24x+4 Do the quadratic equation stuff you learned at school.
What multiplies to 4 and adds up to -4? It's -2. So x=2

And then to find y, plug 0 into x. Everything will multiply to 0 except the 4. So y=4. graph{x^2-4x+4 [-3.096, 8.003, -0.255, 5.294]}
