Question

The graph of f(t) = 5•2^t shows the value of a rare coin in year t What is the
meaning of the yintercept?

Answer 1

Answer:

D.

Step-by-step explanation:

The y-intercept is where the graph crosses the y-axis.

It crosses the y-axis at (0,5).

The graph is of f(t)=5*2^t where t is the number of years and the value of f(t) is the value of that coin after t years.

So we have (0,5) is on the graph of f which means f(0)=5.

f(0)=5 means at t=0 years the value of the coin is $5.

Answer 2

As per the y-intercept of a function, when the coin was purchased, the value of it was $5.

What is the y-intercept of a function?

"The y-intercepts are points where the graph of a function crosses or touches the y-axis of the Cartesian Plane. "

The given function is

$f(t)=5(2^{t})$

As per the graph of the given function, it starts from the point (0, 5).

Hence, it cuts the y-axis at point (0, 5).

Therefore, at the time of purchasing the coin, the value of the coin was at $5.
