<span>Given the table: x f(x) 1 -4 3 -1 4 3 For f(x) = 4(3)^(x - 1) + 4: f(1) = 4(3)^(1 - 1) + 4 = 4(3)^0 + 4 = 4(1) + 4 = 4 + 4 = 8. Thus, f(x) = 4(3)^(x - 1) + 4 does not satisfy the data in the table. For f(x) = 4(3)^(x - 1) - 4: f(1) = 4(3)^(1 - 1) - 4 = 4 - 4 = 0 Thus, f(x) = 4(3)^(x - 1) - 4 does not satisfy the data in the table. For f(x) = 1/4 (3)^(x - 1) + 4: f(1) = 1/4 (3)^(1 - 1) + 4 = 1/4 + 4 = 4.25 Thus, f(x) = 1/4 (3)^(x - 1) + 4 does not satisfy the data in the table. For f(x) = 1/4 (3)^(x - 1) - 4: f(1) = 1/4 (3)^(1 - 1) - 4 = 1/4 - 4 = -3.75 which is approximately -4. f(3) = 1/4 (3)^(3 - 1) - 4 = 1/4 (3)^2 - 4 = 1/4 (9) - 4 = 2.25 - 4 = -1.75 which is close to -1. f(4) = 1/4 (3)^(4 - 1) - 4 = 1/4 (3)^3 - 4 = 1/4 (27) - 4 = 6.75 - 4 = 2.75 which is close to 3. Therefore, f(x) = 1/4 (3)^(x - 1) - 4 satisfy the data in the table.</span>

Answer:

9. No

10. Yes

Step-by-step explanation:

The first one is not, since you have (3, 3) and (3, 9).  In a function, each x maps to a single y.

The second one is since every x appears only once.

kifflom [539]

Answer:

A) 12y^{3}

Step-by-step explanation:

A) \frac{12y^{3} }{6y^{2} }

=\frac{2y(6y^{2} )}{6y^{2}}

= 2y

B) \frac{24y}{6y^{2} }

=\frac{4}{y}

Hence, 12y^{3} is divisible by 6y^{2} and the correct option is (A).
