Answer/Step-by-step explanation:

✔️when x = 0:

[tex] 4^{-x} [/tex]

Plug in the value of x

[tex] 4^{-0} [/tex]

[tex] \frac{1}{4^0} [/tex] (negative exponent)

[tex] \frac{1}{1} [/tex] (whatever number that is raised to the power of 0 = 1)

a = 1

✔️when x = 2:

[tex] 4^{-x} [/tex]

Plug in the value of x

[tex] 4^{-2} [/tex]

[tex] \frac{1}{4^2} [/tex] (negative exponent)

[tex] b = \frac{1}{16} [/tex]

✔️when x = 4:

[tex] 4^{-x} [/tex]

Plug in the value of x

[tex] 4^{-4} [/tex]

[tex] \frac{1}{4^4} [/tex] (negative exponent)

[tex] c = \frac{1}{256} [/tex]
