Answer:
A
Step-by-step explanation:
Answer:
see the explanation
Step-by-step explanation:
we have
Find the inverse of A(x)
Let
y=A(x)
Exchange the variables x for y and y for x
Isolate the variable y
Let
------> function inverse of A(x)
<em>Explanation</em>
For x=1
Find the value of A(x)
The point (1,7) is a solution for A(x)
That means-----> The point (7,1) is a solution for the function inverse g(x)
Verify
For x=7
The point (7,1) is a solution for g(x)
therefore
A(x) and g(x) are inverses of each other if the point (x,y) is a solution of A(x) and the point (y,x) is a solution of g(x)
Answer:
No,
Step-by-step explanation:
No, GCF is not a root, it is the coefficient of x.
If we see an equation in the form y=mx+c (where m and c are just some numbers), but the important thing is that the left hand side is "y" and not "2y" or "3y", then the m is the slope.
So y=5x+7 has a slope of 5 (the number before the x)
And y=2x+7 has a slope of 2 (the number before the x)
So as you move from left to right, the one with greater slope will increase y value faster. Just like if you were climbing two mountains. If you went for 1 kilometre up a really steep mountain, you would be higher up than if you went for 1 kilometre up a less steep mountain.
Another way of saying this is that by changing an equation from slope 5 (steep) to slope=2 (less steep), then "It will increase at a slower rate than before"
