Answer:

Step 2 is wrong.

It should be 3x – <u>18</u> + 4x + 12 – 6x

Explanation:

3(x – 6) + (4x + 12) – 6x →

3x – 18 + 4x + 12 – 6x →

(3x + 4x – 6x) + (-18 + 12) →

x – 6

Determine if the function is an even function an odd function or neither y=2x^4+2x^2
irakobra [83]

Answer:

This function would be even.

Step-by-step explanation:

You can tell a function is even if you plug in -x for x and then simplify and it is the same function. This is the case below.

y = 2x^4 + 2x^2 ----> Plug in -x

y = 2(-x)^4 + 2(-x)^2 ----> Simplify

y = 2x^4 + 2x^2

You'll notice the simplified version is exactly the same as the original, which makes it odd.

The graph of the function f(x)=mx+b contains the points (-1,3) and (-2,4) find m and b
inysia [295]

Answer:

m = -1; b = 2

Step-by-step explanation:

the first step in solving this equation is to find the slope

so we use the equation (y2-y1)/(x2-x1)

so with this the equation is

(4 - 3)/(-2 + 1)

then it would be 1/-1

that is -1

so the function so far is f(x) = -x + b

to find the b you would plug in the coordinates

we can plug in the first set

3 = 1 + b

b = 2

so the m is -1 and the b is 2
