Answer:
8
Step-by-step explanation:
Well, to solve, garph the equation y=x^2+2x-8 and y=0
see where they intersect
anyway the easier way is to factor but anyway
0=(x-4)(x+2)
anyway
solution is x=4 and -2
A and D are answers (they are same)
U can easily put this through a calculator, but it’s 24 :)
Answer:
0.24 to nearest hundredth.
Step-by-step explanation:
f (x)=√x+3
f(2) = √2 + 3
f(8) = √8 + 3
Average rate of change = (√8 + 3 - (√2 + 3)) / (8-2)
= (2√2 - √2)/6
= √2/6
= 0.2357
