What is the maximum or minimum of the quadratic function y = 16x^2 +40x +25
1 answer:
Y = 16x^2+ 40x + 25 <span>The sign before the 16 is positive, so it's a parabola with a minimum. The x coordinate of the minimum is: </span> <span>x=-b/2a=-40/32=5/4=-1.25 </span> <span>If you fill that in, you get y=0 </span> <span>so the coordinates are (1.25, 0)</span>
