Answer:

look at x=0 and plug in 0 for any x you find in the equation

f(0) = 0² - 4*0 +4 = 4

c is out of the race then

let's do this again, but test for x=1 and x=2

f(1) = 1² - 4*1 + 4 = 1

f(2) = 2² - 4*2 +4 = 0

a and b are out

its graph d

when testing like this, choose easy-to-calculate numbers to find out what points you get when asking for the y-value at an arbitrary x-place

Which of the following statements is true?
MakcuM [25]

Answer:

e. All of these statements are true.

Step-by-step explanation:

The first statement is true because an experiment is actually the process by which an observation is made. Consider rolling a die. It is called an experiment because we observe which side of the die lands facing upwards and that number is noted.

The second statement is also true because a simple event is the one which can not be further decomposed into an event. (Compound events can be decomposed into simple events).

The third statement is also true that an event is the collection of one or more simple events. An event can contain either simple events of compound events which are basically a combination of two or more simple events.

Hence, we can say that <u>all the statements are true</u>.
