Refrection over the x-axis changes |x| to -|x|.
Vertical stretch by a factor of 2.5 changes the function to -2.5|x|
Shifting the function down by 3 units changes the function to -2.5|x| - 3

Therefore, f(x) = -2.5|x| - 3

katovenus [111]

Answer:

$333.5

Step-by-step explanation:

First we have to find 45% of 230 and then add that value to 230

(we can also find 145% of 230, which is essentially the same thing)

so 45% of 230 is:

230*(45/100)= $103.5

230+103.5= $333.5

4 Write a recursive formula for the sequence below.<br> f(1) = 3, f(2) = 7, f(3)=11, f(4)=15
iren2701 [21]

Answer:

<u>aₙ = aₙ₋₁ + 4</u>

Step-by-step explanation:

Finding the common difference (d) :

  • d = f(2) - f(1)
  • d = 7 - 3
  • d = 4

Hence, the recursive formula :

  • <u>aₙ = aₙ₋₁ + 4</u>
