Answer: Option C

a> 0

Step-by-step explanation:

The graph shows a radical function of the form f(x)=a(x+k)^{\frac{1}{n}}+c

Where n is a positive number.

For this type of function, if the coefficient a> 0 then then when x tends to \infty f(x) tends to \infty and when x tends to -\infty then f(x) tends to -\infty.

Notice in the graph that as x increases then f(x) also increases and as x decreases f(x) also decreases.

This indicates that the coefficient a> 0

Answer:

  7.84 to 8.16 ounces

Step-by-step explanation:

The difference between the actual amount in the bottle and the target amount of 8 ounces can be at most 2% of 8 ounces. That amount is ...

  0.02×8 oz = 0.16 oz

The amount in the bottle can be this much higher:

  8 + 0.16 = 8.16 . . . ounces

or, it can be that much lower:

  8 - 0.16 = 7.84 . . . ounces

The range of values the bottle could contain is from 7.84 ounces to 8.16 ounces.
