The parabola y=x2y=x2 is changed to the form y=a(x−p)2+qy=a(x−p)2+q by translating the parabola 4 units down and 2 units right and expanding it vertically by a factor of 3. what are the values of aa, pp, and qq?

answer:  

\boxed {\frac{1}{5}}  

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

solution-

60 *   \frac{1}{5}   = 12

90 * \frac{1}{5} = 18

75 * \frac{1}{5} = 15

hence, the answer would be \boxed {\frac{1}{5}}
