To change the shape of a function, you need to stretch or _it.

Step-by-step explanation:

The transformation of functions refers to translation, reflection, compression and stretch. However, translation and reflection only change they position, but not the form. Compression and stretch are the two transformation that actually change the shape of a function, making it bigger or smaller towards one axis.

Therefore, the complete statement would be:

To change the shape of a function, you need to stretch or compress it.

answer: 1inch=7days  

12inch=12*7=84days

step-by-step explanation:

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
