Answer:its the third option c. i did it on edge
Step-by-step explanation:but i dont think im entirely right though....cause i dont remember correctly what i choose so sorry if im wrong
Answer: Second Option
Step-by-step explanation:
The function 
is an exponential function.
Functions of this type have a range that goes from (0, ∞)
When multiplying the function by a negative coefficient 
, now all the values of g(x) will be negative and the range of 
will be: (-∞, 0)
Then we must search among the options a function with range (-∞, 0)
Since the exponential functions of the form 
, where 
always have range (0, ∞) Then the correct option will be the one with a negative coefficient.
The correct option is the second option
Answer:
Option B, Spencer did not factor the polynomial completely; 16x^2−1 can be factored over the integers.
Step-by-step explanation:
<u>Step 1: Factor</u>
256x^4y^2−y^2
y^2(256x^4 - 1)
y^2(16x^2 - 1)(16x^2 + 1)
<em>y^2(</em><em>4x + 1)(4x - 1</em><em>)(16x^2 + 1)</em>

Answer: Option B, Spencer did not factor the polynomial completely; 16x^2−1 can be factored over the integers.
Answer:
8z^3-36z^2+54z-27
Step-by-step explanation:
(2z-3)^3
(2z)^3*(2z)^2*3+3*2z*3^2-3^3
8z^3-3*4z^2*3+3*2z*9-27
8z^3-36z^2+54z-27
