What function is represented in the table?
Pani-rosa [81]

Answer:

c

Step-by-step explanation:

an exponential function of the form

y = ab^{x}

to find a and b use ordered pairs from the table

using (0, 0.5 ) , then

0.5 = ab^{0} [ b^{0} = 1 ] , then

a = 0.5

so y = 0.5b^{x}

using (1, 2 ) , then

2 = 0.5b^{1} = 0.5b ( divide both sides by 0.5 )

4 = b

then exponential function represented by the table is

y = 0.5 (4)^{x}
