Answer:

Step-by-step explanation:
By definition, a relation is a function if and only if each input value have one and only one output value.
The input values are the x-values and the output values are the y-values.
Given the function f(x):

You need to substitute
into this function:

And now you must evaluate in order to find the corresponding output value.
You get:

The function g(x) is:

Then, you need to substitute
in the function:

And finally you must evaluate in order to find the corresponding output value. This is:

AC=AC (reason: reflexive property)

Answer:
-1.596
Step-by-step explanation:
4^(x + 3) = 7
log4 both sides
log4[4^(x + 3)] = log4(7)
(x + 3) × log4(4) = lg7/lg4
x + 3 = 1.403677461
x = -1.596322539
