Marco's equation is correct. Cosine is an even function, which means that for every x, f(-x) = f(x). In other words, you get the same answer for a negative value that you would for its corresponding positive value.

How do you find the slope of a line on a graph?

harina [27]

Find two points on the graph.
example: (1,2) and (3,4)
Using the equation, $\frac{y2-y1}{x2-x1}$ ,will give you the answer.
so for the example, if you plug in the numbers, you get (mobile) 1/3 $\frac{1}{3}$

If f(x) =ax+b ,f(-3)=-4 and f(3)=2, find the value of a and b please help

hichkok12 [17]

Answer:

a = 1

b = -1

Step-by-step explanation:

First, let's make equations out of those given f(x)'s

-4 = -3a + b

2 = 3a + b

We can use elimination method to get rid of the a real quick

-4 = b

2 = b

Add those together

-2 = 2b

Divide both sides by 2

-2/2 = 2b/2

b = -1

Plug in the new b in one of the original equations; I'm gonna use the bottom one

2 = 3a - 1

+ 1 + 1

3 = 3a

3/3 = 3a/3

a = 1
