Answer:
The height of ball when it is at maximum height is 12 unit
Step-by-step explanation:
Given as :
A ball is thrown by child to height y
And y as a function x is y =
So, for maximum value of height ,
= 0
Or , = 0
Or, = 0
Or, = 2
or, x = 12
Hence The height of ball when it is at maximum height is 12 unit Answer
Answer:
f(x) = (4x - 1)(2x + 1)
The zeros of the function are and
.
Step-by-step explanation:
The given quadratic expression is 8x² - 2x - 3.
Now, the factorization of this quadratic expression gives:
f(x) = 8x² - 2x - 3
⇒ f(x) = 8x² - 6x + 4x - 3
⇒ f(x) = 2x(4x - 3) + 1(4x - 3)
⇒ f(x) = (4x - 1)(2x + 1)
Hence, the zeros of the function are and
