"The mean is the average of the numbers: a calculated "central" value of a set of numbers. To calculate it: add up all the numbers, then divide by how many numbers there are." -- Math is Fun
3.25 is the answer so copy down the answer its right
sub x=1 into f(x),
remainder= 1^3+2(1)^2-5(1)-6= -8
since remainder≠0, x=1 is not a root of the function
sub x=-1,
remainder = (-1)^3+2(-1)^2-5(-1)-6= 0
by remainder theorem,
x=-1 is a root of f(x)
hence, the correct ans is c
Answer:
it would be b
Step-by-step explanation:
Sorry if I'm wrong
a = 10
this what I did
7 - 3 = 4 ÷ 0.4 = 10
