Looks like -1357 to me.
I am assuming you mean by the notation
"-5y4" -5 times (y to the fourth power).
Source(s): Just did the arithmetic. - JaredLv 41 decade ago
-5y^4 - 6y² + 9y - 17 when y =4
Just plug in 4 wherever there is a y:
-5(4)^4 -6(4)² + 9(4) - 17 =
-5(256) - 6(16) + 9(4) - 17 =
-1280 - 96 + 36 - 17 =
-1357

-5(4)^4 - 6(4)^2 + 9(4) - 17
-5(256) - 6(16) + 36 - 17

There are 2 a threat intrepretations of this. One is analyzing it rapidly off the website, and the different is analyzing it like a calculator would intrepret the era. Stright foward: -(y^2)-(x^3)+(z^2) =-((-2)^2)-((-3)^3)+((-3)^2) =-4-(-27)+9 =32 Calculator technique: ((-y)^2)-(x^3)+(z^2) =((-(-2))^2)-((-3)^3)+((-3)^2) =4-(-27)+9 =32 the two technique, the respond is the comparable. yet this is not continuously the case.
