For this case we have a function of the form:

y = f (x)

Where f (x) = ab ^ x

The domain of that function is given by all the values that x can take.

If b is a positive real number other than 1 and a> 0, we have that the domain of f (x) is given by (-∞,∞). x can take any value.

On the other hand, the range is given by the dependent values of the variable "y".

IF we evaluate f (-∞) then y tends to zero.

If we evaluate f (∞) then y tends to infinity.

Thus, the range is: (0, ∞)

So, we have:

Domain: (-∞,∞)

Range: (0, ∞)

Answer:

Option C

AfilCa [17]
Assuming you are asking how many weeks, than the answer would be 17-32, because at 16 weeks the growth would be 4 cm, totaling at 11, but you need more than 11cm, and at 32 weeks it's at 15 cm.

Round to the nearest whole number 35, 2, 7, 33, 25, 70, 75, 40, 42, 12, 15, 7, 44, 20, 25, 3, 65, 62

The numbers 35, 2, 7, 33, 25, 70, 75, 40, 42, 12, 15, 7, 44, 20, 25, 3, 65, and 62 are all whole numbers.

  • All natural numbers and 0 are considered whole numbers. They are real numbers without fractions, decimals, or negative integers.
  • Rounding a number implies simplifying it while retaining its value close to what it was. The end output is less precise but more usable.
  • In a given base, a round number is an integer that ends with one or more "0s." So, 590 is more rounded than 592 but less rounded than 600. A round number is frequently understood in both technical and casual language to stand for a value or values close to the nominal value represented.
