how about the first?
im not sure how to do this one
in order to find where the curve intersects the x-axis, you have to set the original function equal to 0.
-1x^2+ 10x= 0
to find the points, plug 0 and 10 back into the original equation
both the y values are 0 because that's where it crosses the x-axis
@hihihii i see where you got x=0 but how'd you get -10?
i got -x+10
and also which is the correct answer to A?
(0,0) or (10,0)? which one do i pick?
hello hello hello
@satellite73 @SithsAndGiggles would anyone kindly like to help?
Finding where the curve intercepts the x-axis is the same as solving for the roots of the equation:
The tangent line to the curve is horizontal when the slope of the tangent line is 0. Hence solve for x in \(f'(x)=0\):
