Write the sets of points from -2 to 5 but exluding 2 and 5 as a union of intervals

we are given

to write the sets of points from -2 to 5 but excluding 2 and 5 as a union of intervals

so, first interval is

-2 to 2 by excluding 2

[-2,2)

Second  interval is

2 to 5 by excluding 2 and 5

so, we can write as

(2,5)

now, we can find total interval

we get

[-2,2) ∪ (2,5)Answer

if x decreases by 4 then y increases by 10

step-by-step explanation:

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
