f(x) =0.02605x-0.01908
Calculate the x-axis intercept for the function above.
Homework Equations
f(x) =0.02605x-0.01908
The Attempt at a Solution
0 = 0.02605x - 0.01908
0.02605x = 0.01908
x = 0.732 (3 s.f.)

I can see that you did that, but what is your question?rollcast said:I'm trying to calculate the x - intercept of the line, f(x) =0.02605x-0.01908.

Just check it by plugging in it into thee original eqn to verify that f(x) is zero.
An x-intercept is the point at which a graph or line intersects the x-axis. It represents the value of x when the function or equation is equal to zero.
To calculate the x-intercept for a function, set the function or equation equal to zero and solve for x. This will give you the x-coordinate of the intercept.
Yes, a function can have multiple x-intercepts if the graph or equation crosses the x-axis at multiple points. These points will each have their own x-coordinate for the x-intercept.
The x-intercept can tell us the value of x when the function is equal to zero, which can be useful in solving equations and understanding the behavior of the function. It can also give us information about the roots or solutions of the function.
Yes, it is possible for a function to not have an x-intercept. This can occur when the graph or equation does not intersect the x-axis, or when the function is undefined at all points on the x-axis.
