Answer:

[see below]

Step-by-step explanation:

A functions input is assigned to exactly one output. This means that the inputs must not repeat.

{(-3, 5), (-2, 5), (0, 5), (1, 5), (2, 5)}

Since no inputs repeat, the relation given is a function.

Hope this helps.

Sean places 28 tomato plants in rows. All rows contain tne same numbers of plants. There are between 5 and 12 plants in each row

Sholpan [36]

Between 5 to 12

There can be 6,7,8,9,10,11

And we can merely calculate that 7 is the one and only factor of 28 according to the question.

So,

There are 7 plants in each row,

2x-5=3x^2 find the root of X

Zina [86]

For this case we must solve the following quadratic equation:

$3x ^ 2-2x + 5 = 0$

Where:

$a = 3\\b = -2\\c = 5$

The roots are given by:

$x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}$

Substituting the values we have:

$x = \frac {- (- 2) \pm \sqrt {(- 2) ^ 2-4 (3) (5)}} {2 (3)}\\x = \frac {- (- 2) \pm \sqrt {(- 2) ^ 2-4 (3) (5)}} {2 (3)}\\x = \frac {2 \pm \sqrt {4-60}} {6}\\x = \frac {2 \pm \sqrt {-56}} {6}$

By definition we have to:

$i ^ 2 = -1\\x = \frac {2 \pm \sqrt {56i ^ 2}} {6}\\x = \frac {2 \pm i \sqrt {56}} {6}\\x = \frac {2 \pm i \sqrt {2 ^ 2 * 14}} {6}\\x = \frac {2 \pm 2i \sqrt {14}} {6}\\x = \frac {1 \pm i \sqrt {14}} {3}$

We have two complex roots:

$x_ {1} = \frac {1+ i \sqrt {14}} {3}\\x_ {2} = \frac {1- i \sqrt {14}} {3}$

Answer:

$x_ {1} = \frac {1+ i \sqrt {14}} {3}\\x_ {2} = \frac {1- i \sqrt {14}} {3}$

Given a polynomial function f(x), describe the effects on the y-intercept, regions where the graph is increasing and decreasing,

Jobisdone [24]

A. When f(x) becomes g(x) = f(x) + 2, the graph of f(x) is shifted upward 2 units.

B The graph of f(x) is reflected in the x-axis and then vertically compressed by a factor of 1/2.
