Question

If f(x) = 2x2 – 3x – 1, then f(-1)=

Answer 1

Answer:  f(-1) = 4

Step-by-step explanation:

f(x) = 2x² - 3x - 1

f(-1) = 2(-1)² - 3(-1) - 1

      = 2(1) + 3 - 1

      = 2 + 2

      = 4

Answer 2

ANSWER:
Given:f(x)=2x^2-3x-1
Then,f(-1)=2(-1)^2-3(-1)-1
f(-1)=2(1)+3-1
f(-1)=5-1
f(-1)=4
