The function f(x)= x^2 is similar to g(x)= -3(x-5)^2+4. describe the transformations. show graphs.

The reflected across x-axis, stretched vertically by factor 3 and shifted 5 units right and 4 units up.

Step-by-step explanation:

The parent function is

The given function is

              ... (1)

The transformations of a quadratic function is defined as

               .... (2)

Where, k is vertical stretch or compression factor, a is horizontal shift and b is vertical shift.

If |k|>1, then graph stretch vertically if 0<|k|<1, then graph compressed vertically. If k<0 or negative, then the graph reflected across x-axis.

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

From (1) and (2) it is clear that

k=-3<0, it means graph reflected across x-axis. |k|=3>1, so graph stretched vertically by factor 3.

a=-5<0, so the graph shifts 5 units right.

b=4>0, so the graph shifts 4 units up.

Therefore the reflected across x-axis, stretched vertically by factor 3 and shifted 5 units right and 4 units up.

answer is

c) 4

step-by-step explanation:

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
