in order to find where the curve intersects the xaxis, you have to set the original function equal to 0. 1x^2+ 10x= 0

x^210x=0 x(x10)=0 x=0, x=10 to find the points, plug 0 and 10 back into the original equation

0+0=0 (0,0) 1(10)^210(10)=0 (10,0) both the y values are 0 because that's where it crosses the xaxis

@hihihii i see where you got x=0 but how'd you get 10?

\[f(x)=x^2+10x\] Finding where the curve intercepts the xaxis is the same as solving for the roots of the equation: \[x^2+10x=0\] The tangent line to the curve is horizontal when the slope of the tangent line is 0. Hence solve for x in \(f'(x)=0\): \[f'(x)=2x+10=0\]
