Answer:
the answer is a
you can subsitute or work backwards
A negative exponent just means that the base is on the wrong side of the fraction line, so you need to flip the base to the other side. For instance, "x^-2" just means "x2, but underneath, as in 1/x^2.
-4^-2 means the power -2 is only applied to 4 and not the negative sign. -4^-2 = -(4^-2), which is equal to -1/16.
Whereas, (-4)^-2 means the power -2 affects on both negative sign and 4. For example, (-4)^2 is equal to (-4 * -4) which is just 16. Moving on, with (-4)^-2 equals to 1/(-4*-4) = 1/16.

Answer:
B. As x approaches negative infinity f(x) approaches positive infinity
Step-by-step explanation:
The given absolute value function is
.
This function has its vertex at (7,-7) and opens upwards.
That means it has a V-shape.
As the values of x grows bigger and bigger negatively or positively, the function f(x) approaches positive infinity.
In other words;
As x approaches positive infinity f(x) approaches positive infinity
As x approaches negative infinity f(x) approaches positive infinity
The correct choice is B.
