Use the graph to determine the domain and range of the relation, and whether the relation is a function.

a.
Domain: {x| -8, 8}; Range: all real numbers; No, it is not a function.
b.
Domain: {x| -8 x 8}; Range: all real numbers; Yes, it is a function.
c.
Domain: {x| -8 x 8}; Range: all real numbers; No, it is not a function.
d.
Domain: {x| -8 x 8}; Range: {y| -12 x 12}; Yes, it is a function.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
