Answer:
B. vertical stretch by 4, translate left by 5
Step-by-step explanation:
When the output of a function is multiplied by a factor, its graph is stretched vertically by that factor. So 4√x stretches √x vertically by a factor of 4. This knowledge by itself lets you select the correct answer choice, B.
When a value is subtracted from the independent variable, the graph is moved (translated) to the right by that amount. Here -5 is subtracted to get √(x+5) from √x. So the graph is translated to the left by 5 units (the opposite of right).
Taken together, these transformations stretch the function vertically by a factor of 4 and translate it left 5 units.

Answer:
Step-by-step explanation:
Just so you can see it easier, 4 inches = 2 feet.
That means you should pick graph C
What my first statement means is that you have to pick some point on the graph that translates to (say) 4 inches to 2 feet. Since that point is clear on graph C, that's what you choose.
A doesn't make that same ratio. It goes 1 to 1. That is 4 inches = 4 feet. That's not the correct ratio
B is 10 inches to 2 feet. That is no where's near the right answer. Just plot the points I'm choosing to see if the ratio holds.
D is 4 inches to 21 feet. Obviously not 2 to 1.
