Answer:
3 and 4
Step-by-step explanation:
Solving the inequality
20 > 4b ( divide both sides by 4 )
5 > b, thus
b < 5
3 and 4 are the only values that make the inequality true
Answer:
B
Step-by-step explanation:
B
the vertex is (-5,-2) which eliminates A and C. D says that the x intercepts are both positive which is obviously incorrect making B the correct answer
First, expand to make it easier
y=x(x^2+5)(x^2+5)
y=x(x^4+10x^2+25)
y=x^5+10x^3+25x
differentiation
y'=5x^4+30x^2+25 is the derivitive
