Answer:
18
Step-by-step explanation:
f(x) = 2(1/3)^x
[x = -2]
f(-2) = 2(1/3)⁻²
= 2(9)
= 18
Answer:
2/(3x-2)²
Step-by-step explanation:
4x²-6x³-2x²+6x³/4x²-6x³-6x³+9x^4=
2x²/4x²-12x³+9x^4=
2x²/x²(4-12x+9x²)=
2/9x²-12x+4
2/(3x-2)²

Answer:
No, this set of ordered pairs does not represent a function.
Explanation:
Functions have one y-value for a given x-value.
Ordered pairs are written (x, y).
In this set, when x=2, it has four y-values (4, 5, 6 and 7), so it cannot be a function.
