A function f(x) is transferred from the parent function p(x) = |x| by a reflection over the x-axis, vertical stretched by a fact or of 2.5 and shifted down 3 units. Write the equation for the function f(x)
1 answer:
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

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
Answer:
x > 1, meaning anything greater than 1
Step-by-step explanation:
solve for x
move the 3 to the right to leave the x by itself
x - 3 + 3 > -2 + 3
x > 1
