How is the function shown below related to y=x? graph the function by translating the parent function. y=x+7 a. each output of y=x+7 is one-seventh the corresponding output for y=x. b. each output of y=x+7 is seven more than the corresponding output for y=x. c. each output of y=x+7 is seven times the corresponding output for y=x. d. each output of y=x+7 is seven less than the corresponding output for y=x.

Parent function: y = x.

Translated function : y= x+7.

We can see that 7 is added to the given parent fuction to get translated function.

We know, f(x) = y + k, if k is a negative number, the graph would shift down and if k is a positive number, the graph would shift up.

Because 7 is added and it is a positive number, parent graph will shift 7 units up.

First we need to plot a graph for parent function y=x.

Then we will move each and every y-coordinate 7 units up ( only y-coodinates will change).

And because it's just addition of 7, it would be 7 more and correct option would be option B.

B. Each output of y=x+7 is seven more than the corresponding output for y=x.

P(centre engine and left fail) = 0.004 x 0.007 = 0.000028
P(centre engine and right fail) = 0.004 x 0.007 = 0.000028
P(all three engines fail) = 0.004 x 0.007 x 0.007 = 0.000000196

P(plane will crash) = 0.000028 x 2 + 0.000000196 = 0.000056196
