Given equation is y=2x which change to y=2x-3 . Now we need to check following which transformations, the equation y=2x changes to y=2x-3 .
Because of -3 with the given function y=2x, the graph shifts to 3 units down. So the transformation is 3 units downwards. If -3 is inside the function that is y=2(x-3), in that case the equation shifts to 3 units right. But since here we have -3 with the function not inside the function, so the equation shifts to 3 units downwards and that's the required transformation .
Ans:
TV = QS
Step-by-step explanation:
Because TV are parallel to QS
so TV is equals to QS
6x^2 - 8 = 4x^2 + 7x
6x^2 - 4x^2 - 7x - 8 = 0
2x^2 - 7x - 8 = 0
discriminant = b^2 - 4ac; where a = 2, b = -7 and c = -8
d = (-7)^2 - 4(2)(-8)
d = 49 + 64
d = 113
the discriminant is greater than zero, so there are two real roots
Answer:
D) It passes the horizontal line test
Step-by-step explanation:
In order for a line to represent a function it must pass the vertical line test.
To apply the horizontal line test, take a pencil and hold it vertically. Then, move it across the graph from left to right. If it intersects the line at 1 point everywhere along the line, then it is a function (functions can only have 1 Y value for every X value).
