Question

If f(x) = 6x – 2 and g(x) = 2x – 10, what is the sum of f(3) and g(2)?

Answer 1

Answer -: Solution

f(x)=6x-2

g(x)=2x-10

f(3)+g(2)=?

We know that

f(x)=6x-2

or,f(3)=6×3+2

=18+2

=20

Now,

g(x)=2x-10

or,g(2)=2×2+10

=4+10

=14

Again,

f(3)+g(2)=20+14

=34

Therefore the sum of f(3)+ f(2) is 34.
