Whích statements describe the function () = ? Check all that apply

26x²-1)

Of(x) has one real zero because it crosses the x-axis once

O flx) 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),

Of(x) crosses the x-axis when x= 1 and x =-1

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

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
