The graph of y = x 2 is changed to y = x 2 - 3. how does this change in the equation affect the graph

see explanation

Step-by-step explanation:

Given the graph of f(x) then f(x) + c is a vertical translation of f(x)

• If c > 0 then shift up of c units

• If c < 0 then shift down of c units

Thus y = x² → y = x² - 3 ← c < 0

Is a vertical shift down of 3 units

answer: -1

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
