AlladinOne [14]

Answer:

Step-by-step explanation:

Let the exponential function given in the picture is,

f(x) = a(b)ˣ

Here, a = Initial value

b = Base value

x = Exponent

Since, the graph passes through the points (0, 1) and (1, 3)

For (0, 1),

1 = a(b)⁰

a = 1

For (1, 3),

3 = 1(b)¹

b = 3

Therefore, equation of the given function will be,

f(x) = (3)ˣ

Therefore, Initial value = 1

Base = 3

Asymptote (Horizontal) → y = 0

Vertical asymptote → None

Domain → (-∞, ∞) Or {x | x ∈ R}

Range → (0, ∞) Or {y | y > 0}

Therefore, answers given by Juan are incorrect.

so,
f(x)=5*2
f(x)=10<span />
