The piecewise function f(x) has opposite expressions. f(x) = StartLayout Enlarged left-brace 1st Row 1st column 2 x minus 1, 2nd column x less-than 0 2nd Row 1st column 0, 2nd column x = 0 3rd Row 1st column negative 2 x + 1, 2nd column x greater-than 0 Which is the graph of f(x)?

its not b

step-by-step explanation:

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

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
