Step-by-step explanation:
f (-3)
1. 2x
= 2(-3)
= -6
2. x -9
= -3 - 9
= -12
3. 2 - 3x
= 2 - 3( -3)
= 2 + 9
= 11
4. 2x³ - 7
= 2(-3)³ - 7
= 2(-27) - 7
= -54 - 7
= - 61
5. 3x² - 2x + 4
= 3(-3)² - 2( -3) + 4
= 3(9) + 6 +4
= 27 + 10
= 37
f(-1)
1. 2x
2( -1)
-2
2. x - 9
-1 - 9
-10
3. 2 -3x
2 - 3(-1)
2 + 3
5
4. 2x³ - 7
2( -1)³ - 7
-2 - 7
-9
5. 3x² - 2x + 4
3(-1)² - 2(-1) + 4
3 + 2 + 4
9
