Le · Answer 1

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

Ana Figueroa · Answer 2

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
