Answer:
x=+/-3
Step-by-step explanation:
x^4-5x^2-36=0
factor
(x^2-9)(x^2+4)=0
split into 2 equations because one of these terms will need to equal zero for the eqation to be true
x^2-9=0 x^2+4=0
x^2=9 x^2=-4
x=+/-3 no real numbers
Answer:
Option C is correct.
The graph is shifted 2 units up.
Step-by-step explanation:
Given the parent function:

To shift the function: We will be adding the number outside the function.
i.e,

- if c > 0, then the function shifted up
- if c < 0 , then the function shifted down.
To shift the function f(x), c= 2> 1 unit up we get g(x) i.e

Therefore, the the graph f(x) change to g(x) which implies that the graph is shifted 2 units up.
So so the sides are x, x√3, 2x
