Question

suppose the exponential regression equation for some data is y=4.97*6.021^x. When x equals 3, what is the predicted value of y? round your answer to the nearest whole number,
A. 1085
B.740
C.74
D.109

Answer 1

Answer:

The correct option is A.

Step-by-step explanation:

The given equation is

$y=4.97\cdot 6.021^x$

We have to predict the value of y at x=3.

Substitute x=3 in the given equation.

$y=4.97\cdot 6.021^3$

$y=4.97\cdot 218.276$

$y=1084.83$

$y\approx 1085$

The value of y is 1085 at x=3. Therefore the correct option is A.
