The following function is quadratic. f(x)=(x+4)(x-6) what is the value of the positive x-intercept of the graph of the related equation y = (x+4)(x-6)?

6

You replace f(x) or y with 0, and then solve for x

y = (x+4)(x-6)

(x+4)(x-6) = y

(x+4)(x-6) = 0

x+4 = 0 or x-6 = 0 zero product property

x = -4 or x = 6

The x intercepts are -4 and 6. In this case, only 6 is the positive x intercept.

side note: The term "root" is another way to say "x-intercept"

it's

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
