Question

Every year 39 million cars cross the Golden Gate Bridge in San Francisco. Which kind of function best models the relationship between time and the cumulative number of cars that have crossed the Golden Gate Bridge, exponential or linear?

Answer 1

Answer:

Linear

Step-by-step explanation:

Hello

Is linear

Best regards

Answer 2

Answer:

Linear

Step-by-step explanation:

Linear function : if the value increases with the constant value per period,

It can written as y = a + bx

Where, a = initial value, b = constant value per period,

Exponential function :  if the value increases with the constant rate per period,

It can be written as,

$y=ab^x$

Where, a = initial value, b = growth factor per period.

∵ Every year 39 million cars cross the Golden Gate Bridge in San Francisco.

Then after x years, the number of cars ( in million )

f(x) = 39x

⇒ f(x) = 0 + 39x

By the above explanation,

Hence, the function that represents the number of cars that have crossed the Golden Gate Bridge is linear.
