Write the equation for an exponential function, in the form y=a x b^x, whose graph though the coordinate points (1,7.5) and (3,16.875).

y = 5*(1.5)ˣ

Step-by-step explanation:

The exponential function is given in the form y = a*bˣ.

Given coordinate points are (1, 7.5) and (3, 16.875).

It means 7.5 = a*b¹ and 16.875 = a*b³

Dividing the second equation by the first equation:-

16.875 / 7.5 = a*b³ / a*b¹

b² = 2.25

b = 1.5

Now substitute the value of b into first equation:-

7.5 = a*1.5

a = 7.5/1.5

a = 5

Hence, y = 5*(1.5)ˣ

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
