Find the \( x \)-and \( y \)-intercepts. If no \( x \)-intercepts exist, state so. \( f(x)=x^{2}+8 x+16 \) A. \( (16,0),(0,-4) \) B. \( (16,0),(0,4) \) C. \( (4,0),(0,16) \) D. \( (-4,0),(0,16) \)

Question 23 Simplify this expression, writing the answer with a rational denominator. \( \frac{1}{\sqrt{3}} \times \frac{1}{\sqrt{3}-1}=\frac{\square+\sqrt{3}}{\square} \)

Find all the zeros of the quadratic function. \[ y=x^{2}-6 x-16 \] If there is more than one zero, separate them with commas. If there are no zeros, click on "None". zero(s): \( \square \)

\( y = f ( x ) = \frac { 1 x - 4 } { 2 x - 6 } \)

г) \( \log _{\frac{1}{5}}^{2}\left(x^{2}+2 x+1\right)-31 \log _{\frac{1}{5}} \frac{x+1}{5}+15<0 \)

Solve. \[ -3 w(w+1)(w+2)=0 \] (If there is more than one solution, separate them with commas.)
