Write an exponential function in the form
y
=
a
b
x
y=ab
x
that goes through points
(
0
,
4
)
(0,4) and
(
3
,
2916
)
(3,2916).

y = 4

Step-by-step explanation:

Using the given points to find a and b

Using (0, 4), then

4 = a ⇒ a = 4, thus

y = 4

Using (3, 2916), then

2916 = 4 b³ ( divide both sides by 4 )

729 = b³ ( take the cube root of both sides )

b = = 9

Thus

y = 4 ← is the exponential function

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
