Question

Draw the graphof the polinomialo _x^2+x+2 find the maximum value of polynomials​

Answer 1

Answer:

$\frac{9}{4}$

Step-by-step explanation:

I assume the polynomial is  - x² + x + 2, in this case function y = - x² + x + 2 has maximum which is y - value of a vertex.

The formula of x-coordinate of a vertex of a parabola is

x = - $\frac{b}{2a}$

For given quadratic function

x = - $\frac{1}{2(-1)}$ = $\frac{1}{2}$

and y-coordinate of a vertex of given function is

y = - ($\frac{1}{2}$)² + $\frac{1}{2}$ + 2 = $\frac{9}{4}$

The maximum of given function is $\frac{9}{4}$
