Answer:
f(x)= x^2 - 2, the one in red.
Step-by-step explanation:
To move a quadratic function up/down, you change the value at the very end of the formula.
So instead of f(x)= x^2 + 1, you would do f(x)= x^2 - 2, to move it down 3. This would be the one in red.

Answer:
137°
Step-by-step explanation:
So, both are equal to each other due to them being the same degree angle.
5x+7=8x-71
subtract 5x on both sides
7=3x-71
add 71 to both sides
77=3x
divide both sides by 3
77/3=x
x equals about 26
insert x into the problems
[5(26)+7]°
this equals 137°
[8(26)-71]°
this equals 137°
