Answer: 121>0   121=11^2  so Discriminant is a perfect square

=> the equation has  2 roots, which real, distint  and  rational

Step-by-step explanation:

D=b^2 -4*a*c

b=5 ( coefficient near x)

a=3 (coefficient near x^2)

c=-8 ( coef without x)

D=25+4*3*8=25+96=121

121>0   121=11^2  so Discriminant is a perfect square

=> the equation has  2 roots, which real, distint  and  rational

Find the critical points and determine if the function is increasing or decreasing on the given intervals.y = 9x^4 + 10x^3Left c
lina2011 [118]
y=9x^4+10x^3

To find the critical points, first we derivate the function:

\frac{dy}{dx}=36x^3+30x^2

dy/dx has roots x = 0 and x = -5/6.

When x < -5/6, we can check that dy/dx is negative. When -5/6 < x < 0, we can check that dy/dx is positive. And, when x > 0, we can check that dy/dx is also positive.

Therefore, y is increasing when x > -5/6 and decrasing when x < -5/6. y has inflection points at x = -5/6 and x = 0
