When Isabella left her house in the morning, her cell phone battery was partially charged. Let BB represent the charge remaining in Isabella's battery, as a percentage, tt hours since Isabella left her house. The table below has select values showing the linear relationship between tt and B. B. Determine the percentage charge that Isabella's phone loses each hour.

5% each hour

Step-by-step explanation:

in 1.5 hours she loses 7.5% of battery

get the percentage of loss for a half hour.

divide 1.5 and 7.5 by 3.

That gives a loss of 2.5% for every half hour.

Which gives a loss of 5% percent an hour.

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
