Calculate x-intercept for f(x)

  1. Feb 23, 2012 #1
    1. The problem statement, all variables and given/known data
    f(x) =0.02605x-0.01908

    Calculate the x axis intercept for the function above.


    2. Relevant equations
    f(x) =0.02605x-0.01908


    3. The attempt at a solution

    0 = 0.02605x - 0.01908
    0.02605x = 0.01908
    x = 0.732 (3 s.f.)

    looks right, I got 0.7324 to 4 sig figures

    Just check it by plugging in it into thee original eqn to verify that f(x) is zero.

    I'm trying to calculate the x - intercept of the line, f(x) =0.02605x-0.01908.

    I can see that you did that, but what is your question?

    I wanted to see if my result was correct as I'm not familiar with the f(x) = ... notation.

    f(0.7324) won't work out to be exactly zero, because of the rounding.
