Step-by-step explanation:
f(x) = 
The parabola opens up, so has a minimum at the vertex.
Let (h, k) be the vertex
h = -b/2a = - (-144)/2(1) = 57
k = 57^2 - 144(57) = 3249 - 6498 = -3249
Therefore, the vertex is (57, -3249)
The minimum value is -3249
The domain is the set of real numbers.
The range = {y | y ≥ -3249}
The function decreases when -∞ < x < 57 and increases when 57 > x > ∞
The x - intercepts:
= 0
x(x - 114x) = 0
x = 0 or x = 114
x-intercepts are (0, 0) and (0, 114)
When x = 0, then we get the y-intercept. So, 0^2 - 114(0) = 0
y-intercept is (0, 0)
Any y = ? equation is a horizontal line that passes through the number given.
y = 7 would be a line passing through 7 on the y - axis and staying flat and never rising.
Hope this helps! ;)
We have to mutiply factor -2/3 times every agument from the parenthesis.

/+8b
8+6b=-4 /-8
6b=-12 /:6
b=-2 - its the answer
