Which of the following is not true if the polygon is a square?

\( r(x)=x^{2} \) on a Punto (1,in)

(i) \( 100 x \times\left(0.01 x^{4}-0.01 x^{2}\right) \)

Question Find the \( x \) - and \( y \)-intercepts of the parabola \( y=25 x^{2}+10 x+1 \). Enter each intercept as an ordered pair \( (x, y) \). Use a comma to separate the ordered pairs of multiple intercepts. You may enter an exact answer or round to 2 decimal places. If there are no solutions or no real solutions for an intercept enter \( \varnothing \). Provide your answer below: x-intercept \( =(\square) \); y-intercept \( =(\square) \)
