Answer:
21b-32+7b-20b
7b-32
Step-by-step explanation:
at x = 0, y = 100, y-intercept
meaning at 0 years, at the very beginning of functioning, the satellite had 100 units of power.
at y = 0, x = 10, x-intercept
meaning, at year 10, the satellite had 0 units of power, already out of power.
Step-by-step explanation:
Here,let x = 1,2,3 and 4
Then,
Domain =(1,2,3,4)
Again,
f(1)= 3*1 + 5
=3 + 5
=8
f(2)=3*2 + 5
=6 + 5
=11
f(3)=3*3 + 5
=9 + 5
=14
f(4)=3*4 + 5
=12 + 5
=17
Therefore, Range=(8,11,14,17)
