Find three solutions for this linear function and choose the correct graph by clicking on it. F -1(x) if F(x) = x + 3
algol13

Answer:

[1,2], [2,1], [3,0]

Step-by-step explanation:

To find F-1(x) if F(x)=x+3 we just need to put -x instead of x.

From our graph(attached) we multiply any three solutions by a -1:

F-1(x)\\\\#For \ x=1\\F-1(1)=-1+3=2\\\\#For \ x=2\\F-1(2)=-2+3=1\\\\#For \ x=3\\F-1(3)=-3+3=0

Hence, the 3 solutions are [1,2],[2,1],[3,0]

Solve x^2+2x+1=0 by graphing
klio [65]
  1. Solutions are − 1 ,2 and  postive 2 and 1 /2 Explanation: When we draw graph of y = x 2 − 2 x − 1 , as a point on x -axis means y = 0 , intercepts on x -axis, give the solution of equation x 2 − 2 x − 1 = 0 Now, if x = 2 , y = − 1 if x = 0 , y = − 1 if x = − 2 , y = 7 if x = 1 , y = − 2 if x = 3 , y = 2 and if x = − 3 , y = 14 So joining points { ( 2 , − 1 ) , ( 0 , − 1 ) , ( − 2 , 7 ) , ( 1 , − 2 ) , ( 3 , 2 ) , ( − 3 , 14 ) } we get the graph graph{x^2-2x-1 [-10, 10, -5, 5]} It shows that intercepts on x -axis are − 1 2 and 2 1 2 Hence, these are the solutions.

REWARDING BRAINLY TO CORRECT ANSWER
xxTIMURxx [149]

Answer:

x - 16 > 8 (lets solve first before we graph)

+16    +16

X > 24

Since X is greater than 24 we need to show that on the number line.

Pick the circle that is hollow,

Put the hallow circle point on 24,

Then make the arrow go to the right of 24 showing that x is greater than 24.
