Question

Find the y-intercept of the quadratic function f(x) = (2x - 5)2​

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

Answer 2

Answer:

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
