Point slope form is:
y − y
= m(x − x)
Where x and y are two known coordinates and m is the slope.
Substitute (4,2) as x and y and 3 as m to find the point-slope form.
<span>y − 2 = 3(x − 4)
</span>
Taking it to the next step would be to turn this into slope-intercept form, y=mx+b
<span>y − 2 = 3(x − 4)
y</span> − 2 = 3x − 12
y = 3x − 10
y − y
Where x

Answer: The function is EVEN.
Step-by-step explanation:
For this exercise it is important to remember that:
1. A function f(x) is even if and only if:
for all "x"
2. A function f(x) is odd if and only if:
for all "x"
So knowing that, and given the following function k(x):
You can plug in for "x", order to know if this is even. Then, you get:
Therefore, since:
You can determine that that the given function is Even.
