Geometric Function

If the image of the function transformation

(x, y) = (x + 2, y − 3) is B’(6,7), what is the pre-image?

• B(10, 4)

• B(8, 4)

• B(4, 10)

• B(8, 10)

Identify the domain.

• J(4, -3), K(-3, 1), L(-2, 0), M(-2, -1)

• J'(4, 3), K'(3, -1), L'(2, 0), M'(2, 1)

Which is the image?

• W(-1, 2), X(2, 5), Y(3, 2)

• W'(-2, -1), X'(-5, 2), Y'(-2, 3)

Given the sequence: 125, 25, 5, .... Write the rule a_n using the geometric sequence formula:

• g_n = (125)(1/5)^(n-1)

• g_n = 625(1/5)^(n-1)

• g_n = 625(5)^(n-1)

• g_n = 125 + 5n

Write the explicit formula for the geometric sequence.

• g_n = 10(2)^n-1

• g_n = 2(10)^n-1

• g_n = 10(2)ⁿ

• g_n = 2(10)ⁿ

Find the common ratio for the geometric sequence.

• 10

• 1/2

• 2

• 4

Write the explicit formula for the geometric sequence.

• g_n = 4(3)^n-1

• g_n = 3(4)^n-1

• g_n = -4(3)^n-1

• g_n = 3(-4)^n-1

Write the explicit formula for the sequence.
