VI 8. Find the equation of the exponential function, in y = a(b) form that passes through the points (3,8) and (9, 42). Round both a and b to the nearest hundredth. An algebraic method must be used for full credit. Remember to use a ^ for exponents. IC Font Family ΑΑΤ Α O tv

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
