What is the value of -√484? select one: a. 242 b. 22 c. -22 d. -242

It'll be -22.

Radicals cannot normally be negative. But the question is asking for the negative of a certain radical, not for a negative radical. It isn't asking, for example, for √-484. It is asking for -(√484).

So √484 is 22, and -(22) is -22.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
