Final answer:
To find the x-intercept of a square root function using a calculator, you need to set the entire function equal to zero and solve for x. The x-intercept is the value of x where the function crosses the x-axis.
Step-by-step explanation:
To find the x-intercept of a square root function using a calculator, you need to set the entire function equal to zero. The x-intercept is the value of x where the function crosses the x-axis.
Here's an example:
If the square root function is f(x) = √(x - 2), you would set f(x) equal to zero:
f(x) = √(x - 2) = 0
Then, solve for x by squaring both sides of the equation:
x - 2 = 0
x = 2
So, the x-intercept is at x = 2
