Question

Given the parent functions f(x) = log10 x and g(x) = 5x − 2, what is f(x) • g(x)?
@ash2326

Answer 1

That symbol between f and g means to multiply.

Answer 2

yes it does

Answer 3

Ok, do you need anymore help then?

Answer 4

lol yes I don't get the problem

Answer 5

How do I do it?

Answer 6

Take the expression that f is equal to and multiply it to the expression g is equal to.

Answer 7

i.e. stick a times sign between them, or just write them next to each other

Answer 8

How do I find out what each expression stands for?

Answer 9

It is given to you f(x)=log_10(x) and g(x)=5x-2

Answer 10

Yeah so how do I solve the expression?

Answer 11

There is really nothing to do here just replace f(x) with what it equals and replace g(x) with what it equals in the expression f(x)*g(x)

Answer 12

Like if I said f(x)=5x and g(x)=sin(x) then f(x)*g(x)=5x*sin(x)=5xsin(x)

Answer 13

you lost me

Answer 14

How about the example,
if f(x)=2x and g(x)=e^x then f(x)*g(x)=2x*e^x=2xe^x

Answer 15

Ok now I'm understanding you more, but i'm getting confused after the = sign.

Answer 16

Or here is another example
if f(x)=4x-2 and g(x)=9x then f(x)*g(x)=(4x-2)(9x)
And if you want you could distribute and say
f(x)*g(x)=(4x)(9x)-2(9x)=36x^2-18x

Answer 17

All I'm doing is saying what f(x)*g(x) is given what f(x) equals and g(x) equals

Answer 18

I'm just replacing f(x) with what it equals and replace g(x) with what it equals

Answer 19

see I donnt know how to get the equal part

Answer 20

You put an equal sign

Answer 21

Or do you mean the part that follows the equal sign

Answer 22

yes that

Answer 23

the part that follows the equal sign is f(x)*g(x)

Answer 24

after the equal part

Answer 25

just the expressions they are equal to instead of saying f(x)*g(x)

Answer 26

Like if I said f(x)=3 and g(x)=2
what is f(x)*g(x)?

Answer 27

6

Answer 28

yes or you could say 3*2 without simplifying right

Answer 29

so what is complicated about what your problem is asking then?

Answer 30

ok.. I'll be right back.
