Question 1058338: Choose the true statement of y is less than or equal to 5x^2 + 6x + 2
Points on the parabola are not solutions
The vertex is (-3/5, 1/5)
The parabola opens down
(0, 0) is not a solution

y=5%28x%5E2%2B%286%2F5%29x%29%2B2
y=5%28x%5E2%2B%286%2F5%29x%2B%283%2F5%29%5E2%29%2B2-5%283%2F5%29%5E2
y=5%28x%2B3%2F5%29%5E2%2B2-9%2F5
y=5%28x%2B3%2F5%29%5E2%2B1%2F5
True, the vertex is (-3%2F5,1%2F5).

0%3C=5%280%29%5E2%2B6%280%29%2B2
0%3C=2
It's true that 2 is greater than 0 so (0,0) is a solution.
False.
