For the function h defined by h(x)=2x2−2, find h(−12)

Given h(x), we can find for the value of h(-12) by simply substituting x with -12 in the equation. Therefore,

h (x) = 2 x^2 – 2

When x = -12

h (-12) = 2 (-12)^2 – 2

h (-12) = 286       (ANSWER)

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.
