Answer:
b
Step-by-step explanation:
In general
Given
y = f(x) then y = f(Cx) is a horizontal stretch/ compression in the x- direction
• If C > 1 then compression
• If 0 < C < 1 then stretch
Consider corresponding points on the 2 graphs
(2, 2 ) → (4, 2 )
(4, - 2 ) → (8, - 2 )
Indicating a stretch in the x- direction.
y = f( ) with C =
 ) with C =  , that is 0 < C < 1
 , that is 0 < C < 1
stretches the graph in the x- direction by a factor of 2
Thus
y = f( ) → b
 ) → b

Answer:

Step-by-step explanation:
Slope intercept form is a way of modeling a quadratic equation, where the coefficient of the term ( ) is the slope (change) of the line, and the constant is the y-intercept. In essence;(
) is the slope (change) of the line, and the constant is the y-intercept. In essence;(  ), where (
 ), where ( ) is the slope and (
) is the slope and ( ) is the y-intercept.
) is the y-intercept. 
The slope of the given line is ( ) because, this is the rate at which the candle burns, therefore, it is the change in the line. The change is (
) because, this is the rate at which the candle burns, therefore, it is the change in the line. The change is ( ) because this is the rate of burning, the slope is also negative since the height is decreasing. (
) because this is the rate of burning, the slope is also negative since the height is decreasing. ( ) is the y-intercept because it is the starting height of the candle. One will take the time since the start of burning the candle, multiply it by the slope, and add it to the y-intercept to find the current height of the candle. Therefore, the equation is (
) is the y-intercept because it is the starting height of the candle. One will take the time since the start of burning the candle, multiply it by the slope, and add it to the y-intercept to find the current height of the candle. Therefore, the equation is ( ), where the output (
), where the output ( ) is the current height of the candle, and the input (
) is the current height of the candle, and the input ( ) is the time at which the measruement was taken.
) is the time at which the measruement was taken.
