Please I need help i would love it if y'all would help me understand!

Step-by-step explanation:

To determine the y-intercept, we need to determine where the function passes through the y-axis, which is where .

According to the rules of the piecewise function, for , we need to use the equation :

Therefore, the y-intercept is .

To determine the x-intercept(s), we need to figure out where the function passes through the x-axis, or where the function is equal to . To do this, we need to set each component of the piecewise function and see where they pass through the x-axis, and if the value is in their set:

For this component of the piecewise function, is in the range of valid values for the component, so is one of the x-intercepts.

Since this value is not , it falls outside the range of valid values for this component, so the only x-intercept for the function is .

which expression represents the approximate length of bc?

i pretty sure it is
