Answer:4x -9 >= -21
4x >= -12
x >= -12/4
x >= -3
so this number line started with -3 and go away till + infinity
hope this will help you
To find the value of f(3) we need to follow the below steps :
Step 1 : First plot the graph of f(x)
Step 2 : We need to find f(3) or the function value at x = 3 therefore, in the graph locate the point (3,0)
Step 3 : Draw a line parallel to Y-axis passing through the point (3,0) .
Step 4 : Now there exists two cases :
If the drawn line do not intersect the graph of f(x), then no value of f(3) exists for the given function of x
If the drawn line intersects the graph, then the intersection point is marked and a line parallel to x - axis is drawn passing through that marked or intersection point. And the line where it intersects the y - axis is our required value of f(3).
If this is wrong than I guess I wasn't smart enough :)
Answer:
y=(x-1)^2 -1
Step-by-step explanation:
If you put it in the form (x-a)^2=b
The answer will be (x-1)^2=1
Answer:
A and C
Step-by-step explanation:
- A right triangle consists of two legs and a hypotenuse.
- To find hypotenuse, we use The Pythagorean Theorem
- The Pythagorean Theorem =
- two legs meet at a 90° angle and the hypotenuse is the longest side
3 - 4 - 5
6 - 8 - 10
7 - 24 - 25
5 - 12 - 13
are some basic right triangle
(about more, look picture)
<em><u>Just use hypotenuse formula :</u></em>
3 x 3 = 9
4 x 3 = 12
5 x 3 = 15
Option C is correct
Option A is correct
But B isn't correct
Hope this helps ^-^
