Answer:
x=-5
Step-by-step explanation:
f(x)=8x+5
-35=8x+5 substitute -35 for f(x).
-40=8x subtract 5 from both sides.
-5=x divide both sides by 8 and then simplify
Answer:
B
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is

Here [ a, b ] = [ - 1, 6 ] and from the graph
f(b) = f(6) = 0
f(a) = f(- 1) = 0, thus
average rate of change =
=
= 0
Answer:
Step-by-step explanation:
assuming that x2 = x², then the equation is y= x²-18
y= x²-18
y-18=x²


so x =
