Answer:

Option (D). G(x) = x³ - x

Step-by-step explanation:

Given function is the attachment,

G(x) = (x - 1.5)³ - (x - 1.5)

This function when translated by left by 1.5 units, rule for the translation is,

G(x) → G'(x + 1.5)

Therefore, translated function will be,

G'(x) = (x - 1.5 + 1.5)³ - (x - 1.5 + 1.5)

G'(x) = x³ - x

Therefore, Option (D) will be the answer.

What is the largest value in the sequence generated by the formula an = –n2 + 6n – 7?
Karolina [17]
Derive the equation and equate the derivative to zero.
                              dan/dt = -2n + 6 = 0
The value of n in the equation is 3. We substitute 3 to the original equation,
                                           an = -(3)² + 6(3) - 7 = 2
The answer to this item is letter B.

Answer:

C. 17/20, rational

Step-by-step explanation:

.25 + 3/5

The least common denominator is 20 so

.25=1/4=5/20

3/5=12/20; therefore,

5/20 + 12/20=17/20.

17/20 is a fraction so is rational.
