Answer:
see attached
Step-by-step explanation:
The equation can be rewritten to vertex form, so you can tell the vertex is at (2, -5). The leading coefficient of 2 means the points will be twice as far apart vertically than they would be if the leading coefficient were 1. A couple of points are shown in the attached.
y = 2(x^2 -4x) +3
y = 2(x^2 -4x +4) +3 -8 . . . . . . complete the square
y = 2(x -2)^2 -5 . . . . . . . . . . . . finish putting in vertex form
<u>ANSWER</u>
Only the equation is a function
<u>EXPLANATION</u>
is graphed above with its inverse
.
We perform the vertical line test for both the equation and its inverse.
The equation
passed the vertical line hence it is a function.
However,
failed the vertical line test, hence it is not a function.
Answer:
h= x/ x+4
Step-by-step explanation:
Move all terms to the left side and set equal to zero, Then set each factor equal to zero.
