Answer:
x - 3 ≥ 0
Step-by-step explanation:
The given function is f(x) = 
Here we need to find the inequality that is used to find the domain of the function.
We should not have negative number inside the square root because if negative number comes inside the square root, then it is not a function.
Therefore, (x - 3) must be greater than or equal to 0
That is x - 3 ≥ 0
We use the above inequality to find the domain of the function.
When we solve the above inequality, we get the domain of the function.
x - 3≥0
add 3 on both sides, we get
x - 3 + 3 ≥ 0 + 3
x ≥ 3
Domain is the set of all real numbers greater than or equal 3.
Therefore, the answer to the question is x - 3 ≥ 0
Answer:
hello :
(2xy)^4 =4x^a (y^b) 4xy
16x^4 y^4 =16x^(a+1) y^(b+1)
a+1 = 4 and b+1 = 4
a=3 and b=3 .......(answer : B)
Step-by-step explanation:
<u>Graph 1</u>
coordinates : (0,-5) (-6,-2)
m = (y2-y1)/(x2-x1)
m = (-2-(-5))/(-6-0)
m = 3/-6 = -1/2
Substitute the values,
y = mx + c
-2 = (-1/2)(-6) + c
-2 = 3 + c
c = -5
Thus, equation is y = -1/2x -5
<u>Graph </u><u>2</u>
coordinates : ( 4,-2) (-5,3)
m = (y2-y1)/(x2-x1)
m = (3-(-2))/(-5-4)
m = 5/-9
Substitute the values,
y = mx + c
-2 = (-5/9)(4) + c
-2 = -20/9 + c
c = 2/9
Thus, the equation is y = -5/9 + (2/9)
Hope it helps :)
Answer: In point-slope form it's y-2=2/3(x-1)
Since you're on a timer I didn't put a explanation if you want a explanation I can put it into this answers comment.
