What are the possible values of b for the following values of c, for x^2 +bx + c if > 0?

If c is greater than 0, than b can be all real numbers that do not equal 0.

Step-by-step explanation:

When looking at the value of c, we know that two factors of c always add up to create b. However, if c is positive, it gives us no indication of the size or sign of the factors and therefore b. Take the example of c = 100. In this instance, b could be -20 or 20. This is because factors of 100 can be -10/-10 or 10/10. We can do this with increasingly larger number, which allows us to assume that b can be both infinitely high or infinitely low.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
