Write an exponential function in the form y = ab that goes through points (0,4)
and (2, 196).

y = 4

Step-by-step explanation:

The form of the exponential function is y = a

Use the given points to solve for a and b

Using (0, 4 ), then

4 = a ( = 1 ), thus a = 4

y = 4

Using (2, 196 ), then

196 = 4b² ( divide both sides by 4 )

49 = b² ( take the square root of both sides )

b = = 7

y = 4 ← exponential function

g

step-by-step explanation:

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
