Answer:
D
Step-by-step explanation:
This questions asks use to find what f(x) or y is, when x is equal to -2.
So, substitute -2 in for x in the equation.
f(x)=2(4)^x
f(-2)=2(4)^-2
Evaluate the exponent. Negative exponents follow this rule:
b^-x= 1/b^x
We have 4^-2. This will become 1/4^2 or 1/16
f(-2)=2(1/16)
Multiply
f(-2)=2/16
This fraction can be simplified. Both the numerator (top number) and denominator (bottom number) can be divided by 2.
f(-2)=2/2 / 16/2
f(-2)= 1/8
The correct choice is D. 1/8

Answer: $100,000
<u>Step-by-step explanation:</u>
Land + Stocks + Bonds + Savings = 100%
+ 0.1x + + 35,000 = 1.00x
= 0.5x + 0.1x + 0.05x + 35,000 = 1.00x
= 0.65x + 35,000 = 1.00x
35,000 = 0.35x
100,000 = x
