Can someone please help me with this problem
Polynomial Interpolation
$q(x) = -\frac{x^2}{10} + \frac{17}{10} x - 3$
$q(15) = -\frac{15^2}{10} + \frac{17}{10} \cdot 15- 3 = 0$
Looks like the peak occurs at x = 7.5. Because of the symmetry of a quadratic the value of y(7.5 + 7.5) will be the same as y(7.5 - 7.5). In other words y(15) = y(0). It is easy to see what this value is on the graph.
So is y(0) the y intercept?
y(0) is the y value when x is 0. So is this the y intercept? What do you think?
Thanks
