Answer:

y = 3/2x + 1

Step-by-step explanation:

I found 2 coordinates: (0, 1) and (2, 4)

Step 1: Find slope

(4 - 1)/(2 - 0) = 3/2 = m

Step 2: Find b

Since you already have the y-intercept at 1, you now write out your entire equation

y = 3/2x + 1

And we have our final answer!

He graph of the function f(x) = –(x + 6)(x + 2) is shown below.
Molodets [167]

The domain of the function is all real numbers, the range of a function is y ≤ 4

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

f(x) = –(x + 6)(x + 2)

If we plot this function on the coordinate plane, we will see it is a graph of a quadratic function.

Here the no other details are given.

But we can say:

  • The domain of the function is all real numbers.
  • The range of a function is y ≤ 4
  • The x-axis intercept will be at (-6, 0) and (-2, 0).

Thus, the domain of the function is all real numbers, the range of a function is y ≤ 4

50% of a certain number is 39. What is the number?
Allushta [10]
Let that certain number be 'n'

50% (n) = 39

50% ⇒ 0.5

0.5 (n) = 39

Divide both sides by 0.5

0.5n = 39
 /0.5    /0.5

n = 78.

So that certain number is actually <em><u>78! :)</u></em>

CROSS CHECK:

50% of 78

0.5 × 78

= 39

Hope this helps! :)
