Answer:

  • x = 8
  • 12 = BD
  • 23 = BE
  • 13 = CE

Step-by-step explanation:

<u>We know that:</u>

  • BD = 2x - 4
  • DE = 2x - 3 - 2
  • BE = 3x - 1
  • CE = 2x - 3

<u>Solution:</u>

  • (2x - 4) + (2x - 3 - 2) = 3x - 1
  • => 2x - 4 + 2x - 3 - 2 = 3x - 1
  • => 4x - 9 = 3x - 1
  • => 4x - 3x = 9 - 1
  • => x = 8
  • => 2x - 4 = BD
  • => 2(8) - 4 = BD
  • => 16 - 4 = BD
  • => 12 = BD
  • => 3x - 1 = BE
  • => 3(8) - 1 = BE
  • => 24 - 1 = BE
  • => 23 = BE
  • => 2x - 3 = CE
  • => 2(8) - 3 = CE
  • => 16 - 3 = CE
  • => 13 = CE

Hence, the answers are:

  • x = 8
  • 12 = BD
  • 23 = BE
  • 13 = CE

Do you agree with the statement that " cubic functions must have at least 1 x-intercept but not more than 3, whereas quadratic f
vladimir2022 [97]

Answer:

Yes, I agree

Step-by-step explanation:

For the cubic function

A cubic function is represented as:

f(x)=ax^3+bx^2+cx+d

A cubic function may have 1, 2 or 3 x intercepts. This is shown below

For 3 x intercepts

y = x^3 - x

Equate y to 0

x^3 - x = 0

Expand

x(x^2 - 1) = 0

Express x^2 - 1 as difference of two squares

x(x - 1)(x +1 ) = 0

<em>x = 0 or 1 or -1</em>

For 2 x intercepts

y = x^3 - x

y  =(x-5)^2)(x+7)

Equate y to 0

(x-5)^2(x+7) = 0

Expand

(x-5)(x-5)(x+7) = 0

<em>x= 5 or x = -7</em>

For 1 x intercept

y = x^3

Equate y to 0

x^3 = 0

Take cube roots of both sides

x = 0

It has been shown above that a cubic function may have 1, 2 or 3.

So, I agree to the statement

For the quadratic function

A quadratic function will not have any x intercept when the function can not be factorized;

E.g.

y = x^2 + x + 17

<em>The above function has no x intercept.</em>

A quadratic function will have at least 1 x intercept when the function can be factorized;

E.g.

y = x^2- 6x + 9

Equate y to 0

x^2- 6x + 9 = 0

Expand

x^2 - 3x - 3x + 9 = 0

(x - 3)(x-3) = 0

x = 3

We've shown that a quadratic may have no x intercept, and it may also have x intercept(s)

Hence, I agree to both statement
