    Answer: - 10

    Step-by-step explanation:

    f (x) = (2x - 5) 2

    f (x) = 4x - 10

    To find y-intercept put x = 0, this is because x is 0 at y-axis line.

    f (0) = 4*0 - 10

    f (0) = - 10

    25

    Step-by-step explanation:

    f (x) = (2x - 5) ²

    f (x) = (2x - 5) (2x - 5)

    f (x) = 4x² - 10x - 10x + 25

    f (x) = 4x² - 20x + 25

    From the function, 25 is the y intercept
