18. Let f(x)=x²+2x+c For what values of care the roots of f(x) not real?
c<_1
c<1
c1
c>1

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

570, the answer is 570, hope it

wait this depends wether emily and zach how they are thinking.

yes they are the same.
