A definitely has to be one because it's a fact and you need to know what it looks like. B isn't true because the greatest integer function rounds down values. C is also not correct because a one-to-one graph has one x-value for every y-value. This one doesn't. D has to be true because f[0] = 0 because the Greatest Integer Function requires it to be. And E is also correct because that's in the definition of a Greatest Integer Function. So, your answers are A, D and E.

Answer: The true options are,

A. This is the graph of the greatest integer function ,

D. f(0)=0

E. f(1.4)=1

Step-by-step explanation:

By the given graph,

f(x) = 0  for 0 ≤ x < 1

f(x) = 1 for 1 ≤ x < 2,

f(x) = 2 for 2 ≤ x < 3,

f(x) = 3 for 3 ≤ x < 4,

.....so, on ....

That is, function f(x) gives integer value for an interval of values,

Since, For all real numbers, x, the greatest integer function gives the largest integer less than or equal to x.

Thus, given function f(x) is greatest integer function.

Also, greatest integer function is a many one function,

So, f(x) is not one to one,

Now, f(x) = 0  for 0 ≤ x < 1, f(x) = 1 for 1 ≤ x < 2

⇒ f(0) = 0 and f(1.4) = 1,

Therefore, option A, E and D are correct.

The smaller triange was dilated to form the larger triangle. What is the value of x?
natka813 [3]

Answer:

x = 14

Step-by-step explanation:

As we can see that the bottom side is equivalent to 3 of the smallest triangle and the side of the larger triangle is equivalent to the 9

This represents that it is dilated by 3 factor

So

= 3 × 3

= 9

Now the other side i.e. 5 of the smallest triangle also need to be dilated by a 3 factor

So the new side is 15

Also the largest triangle is x + 1

So,

15 = x + 1

x = 14
