Question

If f(x) = 2x2 – 3x - 1 then find f(x+2)​

Answer 1

Answer:

f(x)=2x

2

−3x−1

f(x+2)=2(x+2)

2

−3(x+2)−1

=2(x

2

+4+4x)−3x−6−1

=2x

2

+8+8x−3x−7

=2x

2

+5x+1

Answer 2

Answer:

f(x) = 2x² - 3x - 1

f(x + 2) = 2(x + 2)² - 3(x + 2) - 1

= 2(x² + 4 + 4x) - 3x - 6 - 1

= 2x² + 8 + 8x - 3x - 6 - 1

= 2x² + 5x + 1

hope it helps you!!
