Question

What are the important points needed to graph `f(x) = 4 - (x-1)^2`?

Answer 1

At first find the intersecting points
Put the x=0 at first and the f (x)=0 and find the respective values of f (x) and x

Then find the turning point.
Here it'd be (1,4)

since there is a '-' sign, the curve should show a sad face
