Which of the following is an exponential function?
y = 5x
y = 6x
y = log5x
y = x2

Third option is correct.

Step-by-step explanation:

Since we have given that

As we know that logarithm is the opposite of exponential function:

So, it becomes,

On the other hand,

y=5x, y=6x are the linear funtions.

And is the quadratic function.

Hence, Third option is correct.

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480

-14 is the answer

hope this : ))
