Answer:
Step-by-step explanation:
To find the inverse of this function, you need to replace the location of the x and the y.
You start with 
. Now, replace the x and the y, and try to isolate the y.
Hope this helps!
Answer:
1.26 m cubed
Step-by-step explanation:
1.4*.5*1.8= 1.26
You need to foil it out. That's how you get the answer.
(x+4)^20
=
(x+4) x (x+4)^19
=
(x+4)^2 x (x+4)^18
etc.
The graph is a function. When drawing a vertical line, there will be two circumstances:
- The line intersects only one point on a graph.
- The line intersects more than one point on a graph ( POI > 1 )
For the first circumstance, the graph that has only one intersect with a line - it is a function. For the second circumstance, the graph cannot be a function as it gives more than one y-value for a single x-value.
The conclusion is that if a line only has one intersect on a graph then it is a function. Otherwise, not a function but a relation instead. All functions are relations, but not all relations can be functions.
Answer
- The graph passes the vertical line test and is a function.
Your answer is 3
Why? Because 3^4 is 81
same as saying 3 x 3 x 3 x 3=81 :)
