What is the value of the expression below when z = 6

Oduvanchick [21]

Answer:

Step-by-step explanation:

$2z^2+2z-3$

Using PEMDAS/BODMAS, we will have to do the exponent first, which is $z^{2}$ .

Substitute the variable z with 6, since z = 6.

$2(6^{2} )+2(6)-3$

$6^{2} =36$ .

Thus, we will get

$2(36)+2(6)-3$

Solve the multiplication next.

$72+12-3$

Finally, add/subtract the numbers:

$84-3$

$81$

salantis [7]

Answer:

g(-1) = 1

Step-by-step explanation:

Synthetic division is by far the fastest way to evaluate this function at x = -1. Set up synth. div. as follows:

-1 ) 1 6 12 8

-1 -5 -7

----------------------

1 5 7 1

since the remainder is 1, g(-1) = 1
