Question 62719
Question;1

f(x)= (x+2)^2

    = x^2 + 2x + 4


For drawing a graph  of an equation, first of all convert the given equation in terms of x.  That means  y = function of x.

Then give arbitrary values to x in the given equation,  you will get corresponding values  for y.

Using these values, plot the graph.

The graph is,

{{{ graph( 700, 500, -6, 5, -2, 20,x^2 + 2x + 4 )}}}

Question : 2

f(x)= -x^2+3

Graph is,{{{ graph( 700, 500, -6, 5, -20, 5,-x^2 + 3)}}}


Question: 3

f(x)= x^2-2

Graph is,{{{ graph( 700, 500, -6, 5, -4,15,x^2 -2)}}}

Question: 4

f( x) =(x-2)^2

      = x^2 - 4x + 4,
The graph is,

{{{ graph( 700, 500, -6, 5, -4,15,x^2 -4x +4)}}}
