Answer:

f(x) = 16x2 + 32x - 9

 

To find the "zeros", set f(x) = 0:

 

    0 = 16x2 + 32x - 9

 

The equation is solvable by factoring or by using the quadratic formula.  The factors (use the "ac" method) are:

 

    0 = (4x-1)(4x+9)

 

    x = 1/4 = 0.25 and x = -9/4 = -2.25

Which number is an integer? 1, 0.5, 3/2
aksik [14]

An integer is any whole number (not fractions) that can be either negative or positive.

1 is the only integer because 0.5 and 3/2 are not whole numbers and are fractions, while 1 is a whole number.
