What was the net yardage the team had after those 4 plays ?

A loss of 8 yards is represented as -8

Multiply this by 4 to get -8*4 = -32

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
