For the function f(x) = x^2, what effect will multiplying f(x) by 1/4 have on the graph
ELEN [110]

Answer:

B. The graph will be compressed vertically.

Step-by-step explanation:

The given function is f (x) = x²

The new function is f 1 (x) = 1/4 x².

The general function of the form is f(x) = a · x²

i) If |a| < 1   the graph is compressed vertically by a factor of a.

ii)  If |a| > 1  the graph is stretched vertically by a factor of a.

Here:  a = 1/4 < 1

Answer:

B. The graph will be compressed vertically.

Hope this will helpful.

Thank you.

The sum of two numbers is 357 and the difference is 41
dmitriy555 [2]

Answer:

x=199 and y=158

Step-by-step

Let x and y be two numbers

Given that the sum of the two numbers is 357, it may be written as

x+y=357\hfill (1)

difference of the two numbers is 41, it may be written as

x-y=41\hfill (2)

Now adding (1) and (2), we get

x+y=357

x-y=41

_______________________________________

2x=398

_______________________________________

x=\frac{398}{2}                      (Where y is in alternative signs so it may be cancelled)

Therefore

x=199

now substituting x=199 in (1) we get

199+y=357

y=357-199

Therefore

y=158
