Plot the calculated points (0,2) (4,4) and (7,5) on the coordinate grid with a smooth curve

Explanation:

Using the equation #y = sqrt (3x + 4)#
Choose 3 values for #x# such as #0,4, 7#
and find the consequent values for #y#
So if #x = 0# then #y = sqrt(3 xx0 +4)# = #sqrt 4# = #2#

Then
if #x = 4# then #y = sqrt(3 xx 4 + 4)# = #sqrt16# = #4#

and if #x = 7# then #y = sqrt(3 xx 7 +4)# = #sqrt 25# = #5#

Now use these three points to plot the graph
