Suppose that the functions g and h are defined for all real numbers x as follows. g(x) = 2x+2, h(x) = 5x. Write the expressions for (g-h)(x) and (g x h)(x) and evaluate (g+h)(-1).

.

Step-by-step explanation:

Given,

To write:  the expressions for and .

To evaluate :  

As  

 [substituting the values of and ]

So,  

Now,

Now,

So, .

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
