Please help What is the value of x show work

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212

Yvaries directly as x. y =90 when x=6. find y when x=13

The graph of f(x), shown below, has the same shape as the graph of g(x)=x^2,but is shifted up 2 unit.what is the new equation?
