Which of the following exponential regression equations best fits the data shown below?
1 answer:
The exponential regression equation that fits the data is D. y = 8.04.0.98ˣ.
<h3>How to depict the equation?</h3>The quickest way is probably to do direct substitution. First, let's try f(0). The values of y predicted by the four equations are, respectively, 3.14, 5.32, 10.84, and 8.46.
From here, it looks like C and D are the closest to the observed data. Let's try f(4) on C and D.
10.84(1.77)⁴ = 10.84 × 9.815 = 106.4
8.46(3.51)⁴ = 8.46 × 151.4 = 1284
Therefore, the exponential regression equation that fits the data is y = 8.04.0.98ˣ.

Answer:
(1.2, –4.7)
Step-by-step explanation:
Since in the question it is mentioned that on the plane of coordinate, a line is made from point A (7,-2) to point B(-8,-9)
Also, the ratio of A to B is 5:8
Based on this, the x and y coordinates at point C is
= (1.2, –4.7)
Hence, the x and y coordinates of point C is (1.2, –4.7)
Therefore the last option is correct
