Which of the following is true for the relation f(x) = x2 + 8? Only the inverse is a function. Both the equation and its inverse
Alchen [17]

<u>ANSWER</u>

Only the equation is a function

<u>EXPLANATION</u>

f(x)=x^2+8 is graphed above with its inverse f^{-1}(x)=\pm \sqrt{x-8}.


We perform the vertical line test for both the equation and its inverse.


The equation f(x)=x^2+8 passed the vertical line hence it is a function.

However, f^{-1}(x)=\pm \sqrt{x-8} failed the vertical line test, hence it is not a function.

Is P - 1 upon p = 4 find P + 1 upon p whole square​
zlopas [31]

Given that (p - 1/p) = 4, the value of p² + 1/p² is 18. Detail below

<h3>Data obtained from the questio</h3>
  • (p - 1/p) = 4
  • p² + 1/p² = ?

<h3>How to determine the value of p² + 1/p²</h3>

(p - 1/p) = 4

Square both sides

(p - 1/p)² = (4)²

(p - 1/p)² = 16 ....(1)

Recall

(a - b)² = a² + b² - 2ab

Thus,

(p - 1/p)² = p² + 1/p² - (2 × p × 1/p)

(p - 1/p)² = p² + 1/p² - 2

From equation (1) above,

(p - 1/p)² = 16

Therefore,

p² + 1/p² - 2 = 16

Rearrange

p² + 1/p² = 16 + 2

p² + 1/p² = 18

Thus, the value of p² + 1/p² is 18

After the translation, where is A located?
vovikov84 [41]

Answer:

(-3, 13)

Step-by-step explanation:

The transformation that moves a point 4 left and 8 up is ...

 (x, y) ⇒ (x -4, y +8)

The transformation that reflects a point across the y-axis is ...

 (x, y) ⇒ (-x, y)

Applied after the translation, the transformation of ∆ABC becomes ...

 (x, y) ⇒ (-(x -4), y +8) = (4 -x, y +8)

Then point A gets moved to ...

 A(7, 5) ⇒ A'(4 -7, 5 +8) = (-3, 13)
