The inverse is (x + 10)/3
Answer:
The domain is {x:x is a real number}
The range is {y:y is only 4}
Step-by-step explanation:
The domain of the function is the values of x
The range of the function is the values of y
f(x) = 4 is represented graphically by a horizontal line // to x-axis from y = 4
Every point on the this line has different values of x but same value of y
ex: (-1 , 4) , (5 , 4) , ( 0.1 , 4) , ................
So f(x) = 4 is called constant function
Answer:
B
Step-by-step explanation:
you can use foil and the graph,
because you can see (in the graph) that the lines intersect at 1 and 4.
just use foil to help figure out which matches the slope.
something else (the normal way) is find which 2 numbers equal to the last coefficient, in this case it can be
-2 and -2, 2 and 2, 4 and 1 or -4 and -1, multiply them and if they make up the last coefficient, and added it equals the second coefficient it is correct.
Answer:
(1,-3)
Step-by-step explanation:
The reason why it would be (1,-3) is because (1,3) is in the first quadrant which is (+,+) and when it is reflected across the x axis, it is then placed into the fourth quadrant which is (+,-). So you need to make the 3 negative and then it will be reflecting across the x axis
Step-by-step explanation:
A(-2;1)
B (6;5)
(y-yA)/(yB-yA)= (x-xA)/(xB-xA)
(y-1)/4=(x+2)/8
8y-8=4x+8
8y=4x+16
y=½x+2 that is x-2y+4=0
