Which relation is a function? Group of answer choices (2, 7), (6, 5), (4, 4), (3, 3), (2, 1) (9, −3), (9, 3), (4, −2), (4, 2), (

Given:

The relations in the options.

To find:

The relation which is a function.

Solution:

Consider the options are :

(a) {(2, 7), (6, 5), (4, 4), (3, 3), (2, 1)}

(b) {(9, −3), (9, 3), (4, −2), (4, 2), (0, 0)}

(c) {(1, 0), (3, 0), (1, 1), (3, 1) (1, 3)}

(d) {(1, 1), (2, 2), (3, 3), (4, 4), (5, 8)}

A relation is a function if there exist a unique y-value for each x-value.

In option (a), y=7 and y=1 at x=2. So, it is not a function.

In option (b), y=-3 and y=3 at x=9. So, it is not a function.

In option (c), y=0 and y=1 at x=3. So, it is not a function.

In option (d), there are unique y-value for each x-value. So, it is a function.

Therefore, the correct option is (d).

Which of the following is an equivalent form of the compound inequality −22 > −5x − 7 ≥ −3? (1 point)

alisha [4.7K]

$- 22 > - 5x - 7 \geqslant - 3$
is the same thing as
$- 22 > - 5x - 7$
and
$- 5x - 7 \geqslant - 3$
Therefore, the first option is correct.

I need the answer plz

Answer:

I can't solve and show it but only tell a method to do it!

So find the zero of the given factor:

i.e.

$(x + 1) \\ x = - 1$

Now put its value (-1) in the polynomial

${x}^{3} - 13 {x}^{2} + 32x - 20$

Now if the answer comes zero it is a factor.

You'll get your answer!
