Question

Define the following functions .
f(x)=x^2; g(x)=1/√x

a.f+g
b.f-g
c.f⋅g
d.f/g
e.g/f

Answer 1

.f+g=x^2+(1/√x)
f-g=x^2-(1/√x)
f⋅g=x^2*x^(-1/2)=x^3/2
f/g=x^2*x^(1/2)=x^5/2
g/f=(1/√x)/x^2=x^-1/2 * x^-2=x^-5/2

Answer 2

a&b cant be operated?

Answer 3

@MysteryOwl
A=x not =0
b=x not=0
c=for all value of "x"
d=for all value of 'x'
e= not =0

Answer 4

uhmm.. can you explain further please?
