Answer:
Step-by-step explanation:
Part A)
For equation f(x) = 2x² - 5x + 3, to find x intercepts let y=0 then solve x,
2x² - 5x + 3 = 0 -> (2x + 1)(x -3) = 0 , can find x - intercepts from here
x = ____ and ____
Part B)
To find if vertex is a max or min, compare to equation y = ax² + bx +c
if a > 0 then parabola opens up and vertex is a minimum.
if a < 0 then parabola opens down and vertex is a maximum,
thus vertex is a minimum in this problem
to solve vertex set x = -b / 2a = 5 / 2(2) = 5/4
solve for y value
.... vertex is then at point ( 5/4 , y value found)
Part C)
Can plot the intercepts and vertex points

Answer: (7+1) + 20
Step-by-step explanation:
Answer:
2016in^3 more water is needed.
Step-by-step explanation:
Take the three sides and multiply them together
14in*24in*12in=4032in^3
Since only have the tank is full divide your answer by 2
4032/2=2016in^3
To get your final answer of 2016in^3.
