Set the equation equal to zero. For example, take the function

F(x) = x^2 - 4

Find the zeroes by

x^2 - 4 = 0

x^2 = 4

sqrt(x^2) = sqrt(4)

x = +/- 2

How many zeros are there from 1 to 1000?

To find the number of zeros from 1 to 1000, we can count the zeros in each digit position (units, tens, and hundreds). In the range from 1 to 999, there are 300 zeros (100 from each of the hundreds, tens, and units places). Therefore, including the number 1000, which has three zeros, the total count of zeros from 1 to 1000 is 303.


How does knowing the zeros of a function help determine where a function is positive?

Knowing the zeros of a function helps determine where the function is positive by identifying the points where the function intersects the x-axis. Between these zeros, the function will either be entirely positive or entirely negative. By evaluating the function's value at points between the zeros, one can determine the sign of the function in those intervals, allowing us to establish where the function is positive. This interval analysis is crucial for understanding the function's behavior across its domain.


If a function is positive at a test number does the function has no zeros?

false!


State whether the following is a polynomial function give the zero s of the function if the exist f x x 2-6x plus 8?

The function ( f(x) = x^2 - 6x + 8 ) is a polynomial function because it is a quadratic expression. To find the zeros, we can factor it as ( (x - 2)(x - 4) ), which gives us the zeros ( x = 2 ) and ( x = 4 ). Thus, the zeros of the function are 2 and 4.


Can you determine the zeros of f x squared 64 by using a graph?

Yes, you can determine the zeros of the function ( f(x) = x^2 - 64 ) using a graph. The zeros correspond to the x-values where the graph intersects the x-axis. By plotting the function, you can see that it crosses the x-axis at ( x = 8 ) and ( x = -8 ), which are the zeros of the function.

What are the zeros of a polynomial function?

the zeros of a function is/are the values of the variables in the function that makes/make the function zero. for example: In f(x) = x2 -7x + 10, the zeros of the function are 2 and 5 because these will make the function zero.
