Evaluate the function y= -3 (1/4) for x =-3 on top of the 1/4 is where the x goes. so it is 1/4 x

earnstyle [38]

$\text{Consider the function}\\
\\
y=-3\left ( \frac{1}{4} \right )^x\\
\\
\text{now to evaluate the value of the function at }x=-3, \text{ we substitute}\\
x=-3 \text{ in the given function and solve further for y.}\\
\\
\text{so we get}\\
\\
y=-3\left ( \frac{1}{4} \right )^{-3}\\
\\
\text{now using the exponent property, }\left ( \frac{1}{a} \right )^{-m}=(a)^m, \text{ we get}\\
\\
y=-3(4)^{3}\\
\\
\Rightarrow y=-3(64)\\
\\
\Rightarrow y=-192$

so the value of the function at x=-3 is -192

baherus [9]

I light year = 9.46 x 10¹² km

-------------------------------------------------------------------------------------
Find the number of light years
-------------------------------------------------------------------------------------

$\text {Number of light years = } \dfrac{6.8 \times 10^{13}}{9.46 \times 10^{12}}$

$\text {Number of light years = } 7.18$

-------------------------------------------------------------------------------------
Answer: The distance from Earth to the star is 7.18 light-years.
