Keep these rules in mind:

  1. (a + b)² = a² + 2ab + b²
  2. (a - b)² = a² - 2ab + b²
  3. (a + b)(a - b) = a² - b²

Firstly, solve the exponent and multiplication:

4x^2-20x+25-0.5x

Next, combine like terms:

4x^2-20.5x+25

Next, subtract 4x² on both sides:

-20.5x+25

Next, subtract 25 on both sides:

-20.5x

Lastly, divide both sides by -20.5. And since you are dividing by a <u>negative</u>, flip the inequality sign:

x>2

<u>Your answer is x > 2.</u>

What is the vertex of the graph of f(x) = |x 3| 7? (3, 7) (7, 3) (–3, 7) (7, –3).
KatRina [158]

The vertex of the given modulus function is (3,-7).

Given information:

The given modulus function is,

f(x)=|x-3|-7

It is required to find the vertex of the given function.

<h3>What is the vertex of a modulus function?</h3>

Modulus function is in the shape of V. The notch of V is the vertex of the function.

The given function can be defined as,

f(x)=x-10;x\geq3\\&#10;f(x)=-x-4;x

From the above function, it can be concluded that the vertex of the function should be (3,-7). Also shown in the attached image.

See the attached image.

Therefore, the vertex of the given modulus function is (3,-7).
