Write the equation of each function Solution1 a even functio

Solution

1) a) even function symmetrical about the y axis

Its a parabolic curve: y = x^2

b) y= 1/x

c) Mod function with y +ve for x<0 and x>0

so, y = |x|

d) y = sqrtx as x >0

e) graph is symmetrical about origin and its an odd function passes

through( 1,1) and ( -1, -1)

y = x^3 cubic function
