75% increase followed by 50% decrease is it greater than to original
IceJOKER [234]

Answer:

  • Set original amount = x

<u>After a 75% increase, it would become</u>

x + 75%x = x + 0.75x = x(1 + 0.75) = 1.75x

<u>After a 50% decrease, it would become</u>

1.75x - 50%(1.75x) = 1.75x - 0.5(1.75x) = 1.75x - 0.875x = 0.875x = \frac{7}{8} x

Because \frac{7}{8} x is less than x, the new amount would be less than the original.

List the sequence of transformations. ()=−2(−3)^4+1
SVEN [57.7K]

We have the function:

()=−2(−3)^4+1

We need to go from this equation to the parent function x^4. To do that, we first do a vertical translation of 1 unit below. That is:

Vertical translation: f(x) - 1

= −2(−3)^4

Now, we make a horizontal shift of 3 units to the left, replacing x by x + 3:

f(x + 3) + 1 = −2()^4

Horizontal shift: f(x + 3) - 1

= −2x^4

We can make a horizontal expansion if we multiply this function by 1/2:

Horizontal expansion: ( f(x + 3) - 1 ) / 2

= -x^4

Finally, we make a reflection around the x-axis by multiplying this result by -1:

x-axis reflection: -( f(x + 3) - 1 ) / 2

= x^4

HELP MEEEE<br> How do you add and subtract functions?
nata0808 [166]

Answer:

To add or subtract functions, just add or subtract the values at each point where it makes sense. If the functions are given by formulas, you can just add or subtract the formulas (it doesn't matter whether you plug in values before or after).
