Problem
evaluate the function
f(-x) = f(x)
plug in the points (2,1) then solve
Solution
For this case we can conclude that:
f(2) =1
So then we satisfy that:
f(-2) =1
Option B:
The perimeter of the figure is 16 + 2π.
Solution:
The clear image of the question is attached below.
Diameter of the semicircle = 7 – 3 = 4
Radius of the semicircle = 4 ÷ 2 = 2
Perimeter of the semicircle = 
In figure, one side of the semicircle is merged with rectangle, so remove two radius from the perimeter of the semicircle.
Perimeter of the semicircle =

= 2π units
Perimeter of the rectangle given = 3 + 7 + 3 + 3
= 16 units
Perimeter of the given figure = 2π + 16
= (16 + 2π) units
Hence the perimeter of the figure is 16 + 2π.
Option B is the correct answer.
3 times X squared minus 4 times X =

Answer:
y=-11
Step-by-step explanation:
A line can be represented by a linear equation of

where m is the slope and y is the y intercept.
The slope is 0 so this function will be

Which is also called a constant function. The y intercept is -11. So the answer is

2/3 - 3/4
x - 3
x= (2/3 * 3) / (3/4) = 2 * (4/3) = 8/3 = 2 and 2/3 of tablespoon of salt
