It's just recursive.
The initial value is 21 and rate of change is 16 pages per week
<em><u>Solution:</u></em>
Given that After writing part of his novel, Thomas is now writing 16 pages per week
After 4 weeks, he has written 85 pages.
Given that assume the relationship to be linear
Linear relationships can be expressed either in a graphical format or as a mathematical equation of the form y = mx + c
y = mx + c
where "y" is the number of pages written after 4 weeks
x = 4 weeks and m = 16 pages
Therefore,
85 = 16(4) + c
85 = 64 + c
c = 85 - 64
c = 21
Therefore, initial value is 21 and rate of change is 16 pages per week

Answer:
f(-4)= -2
Step-by-step explanation:
f(x)=x^2+5x+2 find(-4)
replace x= -4 in function
f(-4) = (-4)^2+ 5*-4+2
= 16 -20 +2
= 18-20
= -2
