Answer:
C. f(x) = 40(1/4)^x
Step-by-step explanation:
Check all the options:
When x = 0
A. f(x) = 1/4(40)^x
f(x) = 1/4(40)^0
f(x) = 1/4(1)
f(x) = 1/4
When x = 0
B. f(x) = 1/2(40)^x
= 1/2(40)^0
= 1/2(1)
f(x) = 1/2
When x = 0
C. f(x) = 40(1/4)^x
= 40(1/4)^0
= 40(1)
= 40
When x = 0
D. f(x) = 4(1/3)^x
= 4(1/3)^0
= 4(1)
= 4
They are called ordered pairs. (x,y)
5²-0²=25
5 can represent x, making x² equal to 25
If 0 represents y, there will not be any change to the 25, fulfilling the equation given.
x= 5
y= 0
2^-5 simplified in decimal form is 0.03125
5^-3 simplified in decimal form is 0.008
10^-4 simplified in decimal form is 0.0001
