Which statements describe the function f(x)=2x-5/2(x^2-1)? Check all that apply.
f(x) has one real zero because it crosses the x-axis once.
f(x) has two real zeros because it crosses the x-axis twice.
f(x) has real zeros at 1 and –1.
f(x) has a real zero at 2.5.
f(x) has x-intercepts at (1, 0) and (–1, 0).
f(x) crosses the x-axis when x = 1 and x = –1.
f(x) has an x-intercept at (2.5, 0).

1) f(x) has one real zero because it crosses the x-axis once.

2) f(x) has a real zero at 2.5.

3) f(x) has an x-intercept at (2.5, 0).

Step-by-step explanation:

The function can be reorganized as follows:

There is one real zero (numerator) in the function (x-intercept), which is . Besides, and are poles (denominator), that is, x-values so that function is undefined.

Lastly, the correct answers are described below:

1) f(x) has one real zero because it crosses the x-axis once.

2) f(x) has a real zero at 2.5.

3) f(x) has an x-intercept at (2.5, 0).

add 5 subtract 1

step-by-step explanation:

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
