Answer:

The first amount is larger by 25% or .25a

Step-by-step explanation:

Lets increase a by 50%

The increase is .5a

So the new value is a + .5a = 1.5a

Now we will decrease the new value by 50%

decrease = .5 (1.5a) = .75a

The new value of a is 1.5a - .75a = .75a

a > .75a

a - .75a = .25a

a is bigger than .75a by .25a

Which of the following is an even function?

nika2105 [10]

Answer:

An even function is:

f(x) = 7

Step-by-step explanation:

An even function accomplish the following condition:

f(x)=f(-x) (1)

Applying (1), we have:

f(x)= (x-1)^2 $\neq$ f(-x) $\neq$ (-x-1)^2
f(x)= 8x $\neq$ f(-x) $\neq$ -8x
f(x)= x^2 -x $\neq$ f(-x) $\neq$ (-x)^2 +x

f(x)=7 = f(-x)= 7

The last one is even.
