Find the y-intercept for the parabola defined by
this equation:
y = 4x2 + 9x + 5
Separate the values with a comma.

1 3 5

step-by-step explanation:

i took the test: )

other answer is correct. i had used the radius of the radius somehow. a website:

i believe it is the square root of 122 because when you turn it on it's side, to where the 5 inches is on the bottom, it looks like it is the same length.

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)
