What is the value of a for the exponential function in the graph represented in the form of f(x)=a(b^x)

Rina8888 [55]

Note: The complete question, along with the graph, is attached below.

Answer:

The value of a = 3

Step-by-step explanation:

Given the function

$f\left(x\right)=a\left(b^x\right)$

From the attached graph, it is clear that

at x = 0,

$f\left(0\right)=a\left(b^0\right)$

$\:f\left(0\right)\:=\:a\:\times \:1$ ∵ $b^0=1$

$f\left(0\right)=a$

Thus

When x = 0, the y-intercept will be:

$f\left(0\right)=a$

From the attached figure, it is clear that

at x = 0, the value of y = 3

putting y = 3 in the equation

$f\left(0\right)=a$

3 = a ∵ $f\left(0\right)=y=3$

Therefore, the value of a = 3

At most Nate can run 0.1 of a mile in a minute. If he is given 13.9 minutes to run as far as he can, how many miles dan Nate run

nadezda [96]

(.1mi/1min)
1.39mi/13.9 min
You have to multiply the bottom and the top by the same number to get the answer, you're trying to make the denominator 13.9 for the amount do minutes so you multiply the numerator by 13.9 to get the numerator
