The value of a, b, c, d, e, and f are 1, 1/16, 1/256, 1, 4/9, and 16/81 after plugging the values of x.
What is an exponential function?
It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a×
where a is a constant and a>1
We have:
y = 4⁻ˣ
x = 0
a = 4⁻⁰ = 1
x = 2
b = 4⁻² = 1/16
x = 4
c = 4⁻⁴ = 1/256
y = (2/3)ˣ
x = 0
d = (2/3)⁰ = 1
x = 2
e = (2/3)² = 4/9
x = 4
f = (2/3)⁴ = 16/81
Thus, the value of a, b, c, d, e, and f are 1, 1/16, 1/256, 1, 4/9, and 16/81 after plugging the values of x.
