For the given function, determine consecutive values ofx betveen which each real zero is located
f) =-11xt- Sr?-912+12r+ 10
O There are zeros between 00 x = l and x = 0, x=0 and x =-100.
There are zeros between x =2 and x = 3, x=l and x= 2, 0x=-i and x = -2, x=-1 and x = -2, x--
2 and x =-3.
There is a zero between 00x=0 andx=1.
There isa zero betiween x =0 and x =-100.

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
