Answer:
The correct option is A) Down.
Step-by-step explanation:
A function can be shift vertically up or down by adding some positive or negative constant.
For example:
Consider the figure 1:
The function shifted up by <em>k</em> unit. (where <em>k</em> is 1 unit)
Now consider the figure 2:
The function shifted down by <em>k</em> unit. (where <em>k</em> is 1 unit)
Which means to shift the graph of an equation certain number of units up, we need to add that number from the functions equation.
Similarly, to shift the graph of an equation certain number of units down, we need to subtract that number from the functions equation.
Therefore, the correct option is A) Down.
Let x = your number.
x^2 - 21 = 4x. Subtract 4x from both sides.
x^2 - 4x - 21 = 0. Factor.
(x - 7) (x + 3) = 0. Set each term to 0.
x + 3 = 0. Subtract 3 from both sides.
x = -3. This is the negative solution.
Set the other term equal to zero.
x - 7 = 0. Add 7 to each side.
x = 7. This is the positive solution.
Answer:
yes their just 2 answer choices
right E units, down A units
whenever you have ( -E) whatever you have Inside you do the opposite just like this problem. We have -E so to the right. if it was positive we go left
