Question

2. Based on the table below, determine the exponential function being used. Use x as your variable. Then, evaluate this expression for x=7.

Answer 1

Answer:

$y=5^{x}\\y=5^{7}=78125$

Step-by-step explanation:

$y = a^{x}, a=5\\y=5^{x}\\y=5^{0}=1\\y=5^{1}=5\\y=5^{2}=25\\y=5^{3}=125\\and\\y=5^{7} = 78125$
