Answer:

The third one, fourth one, and sixth one.

Step-by-step explanation:

If there are repeating x values in the domain, the function would not be valid, for vertical lines would form. Every input (domain) must only have one output (range), but every output can have multiple different inputs.

Find the value of expression - 17x-19xpwer4 - 21x power 2,when x=3

Marrrta [24]

Answer:

$-17x - 19x^4 - 21x^2 = -1779$ when $x = 3$

Step-by-step explanation:

Given

$-17x - 19x^4 - 21x^2$

$x = 3$

Required

Solve

Substitute 3 for x in $-17x - 19x^4 - 21x^2$

$-17x - 19x^4 - 21x^2 = -17*3 - 19*3^4 - 21*3^2$

Evaluate all exponents

$-17x - 19x^4 - 21x^2 = -17*3 - 19*81 - 21*9$

$-17x - 19x^4 - 21x^2 = -51 - 1539- 189$

$-17x - 19x^4 - 21x^2 = -1779$
