For the given function, determine consecutive values of x between which each real zero is located. f(x) = –11x4 – 5x3 – 9x2 + 12x + 10
Options:
There are zeros between x = 2 and x = 3, x = 1 and x = 2, 0 x = –1 and x = –2, x = –1 and x = –2, x = –2 and x = –3.
There is a zero between x = 0 and x = –100.
There is a zero between 00 x = 0 and x = 1.
There are zeros between 00 x = 1 and x = 0, x = 0 and x = –100.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

pi times x squared
