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

    That symbol between f and g means to multiply.

    How do I do it?

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

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

    How do I find out what each expression stands for?

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

    Yeah so how do I solve the expression?

    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)

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

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

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

    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

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

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

    see I donnt know how to get the equal part

    You put an equal sign

    Or do you mean the part that follows the equal sign

    yes that

  23. myininaya

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

    after the equal part

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

  26. myininaya

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

    yes or you could say 3*2 without simplifying right
