Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 1/2(4)ˣ
f(3) is x = 3
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(3) = 1/2(4)³
- Exponents: f(3) = 1/2(64)
- Multiply: f(3) = 32

Answer: y = 2x^4
The graph represents a parabolic-looking shape so it's either a quadratic or some even degree polynomial. This rules out y = -2x^3 and y = 2x^3 as they are cubics with odd degrees
The degree of a polynomial is the largest exponent. It determines the end behavior. In this case, both ends are rising upward together. Because they are rising up in the positive y direction, this means that we cannot have y = -2x^4 as the answer. For example, if x = 2 then y = -2*x^4 = -2*2^4 = -32, but the point (x,y) = (2,-32) isn't on the blue curve. So we can rule y = -2x^4 out.
The fact that y = 2x^4 has a positive leading coefficient tells us that the endpoints point upward.
Answer:
C
Step-by-step explanation:
This question can simply be answered by the process of elimination. All of the other answers have numbers behind the first number of the decimal. when you are rounding to the nearest tenth, you will have no numbers behind the decimal except 1. They will look like this:
11.70
23.30
45.60
So, since we are looking for the nearest tenth, we would choose C because it is the only one that is rounded.
C
Step-by-step explanation:
pi goes on infinitely so no matter what its multiplied by it would go on infinitely
