All are the exponential function.
<h2>Exponent</h2>
Exponential notation is the form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter is called the base. It indicates that the base is to raise to a certain power. c is the base and x is the power.
<h3>Which functions represent exponential growth?</h3>
1. y = f(x) is a exponential function.
Because the range of the exponential function is from 0 to ∞ for all values of x. And it is 1 at x = 0.
2. y = h(x) is a exponential function.
Because the range of the exponential function is from 0 to ∞ for all values of x. And it is 1 at x = 0.
3. y = g(x) is a exponential function.
Because the range of the exponential function is from 0 to ∞ for all values of x. And it is 1 at x = 0.
4. y = k(x) is a exponential function.
Because the range of the exponential function is from 0 to ∞ for all values of x. And it is 1 at x = 0.
Thus, all are the exponential function.

Answer:
$24.00
Step-by-step explanation:
x = per month
y = per song
t = total
Equation:
t = 14x + 0.5y
t = 14(1) + 0.5(20)
t = 14 + 10
t = 24
Answer:
C. 
Step-by-step explanation:
We have been given a function formula 
. We are asked to find the axis of symmetry for the given function.
We can see that our given function is a parabola in vertex form. We know that vertex from of parabola is 
, where (h,k) represents vertex of parabola.
Let us convert our given function in vertex form as:
We know that axis of symmetry of a parabola is the equation of x-coordinate of vertex, which in form 
.
Since the x-coordinate of vertex is 
, therefore, the axis of symmetry for the given function would be .
6x+$3.20=$18.20
Subtract 3.20 from both sides
6x=$15
x=$2.50
Check:
6(2.50)+3.20=18.20
$15+$3.20=$18.20
