y intercept means x=0
y=-(0-4)^2-25
y=-16-25
y=-9

y= -(x-4)² - 25
= -(x² - 8x + 16) - 25
= -x² + 8x - 41
The y-intercept is the value of the function for x=0:
y-incp = -0² + 8â0 - 41 = -41

no, the y- intercept is
you set x=0. then -4 times -4= 16 but then you account for the negative in front of the parentheses, so it is -16 then minus another 25
u get -41

-41. To find the y-intercept, set x=0 and solve for y

y-intercept:
(0, __)
y = -(0-4)^2 - 25
y = -(-4)^2 - 25
y = -(16) - 25
y = 9
y-intercept: (0,9)
