Hi I have a couple questions on how to find the x and y intercepts.

For the equation y=x sqrt x+2 , I don't understand how to find the x and y intercepts. sqrt= square root

Also for the equation, y= |x-2|-4 , I also don't quite understand completely how to find the x and y intercepts either.

If someone could help me that would be great! I really need help on math and u guys were great the other time you helped. Thank you. :grin:

For y-intercept, set x = 0 and evaluate the function.

For example, if the function is y = m*x + b,

y-intercept = m*0 + b = b

For x-intercept, set y =0 and evaluate value for 'x'.


For example, if the function is y = m*x + b,

0 = m * (x_intercept) + b

x_intercept = - b/m (where m<>0)
