Question

if f(x) =x^2 +5x -1 , then f (2) +f (-3)
​

Answer 1

Answer:

ok......

Step-by-step explanation:

Given, f(x)=3x

2

−5x−4 .......(1)

So f(−2x)=12x

2

+10x−4

⇒2f(−x)=6x

2

+10x−8...... from (1)

⇒−f(x)=−3x

2

+5x+4

⇒4f(x)=12x

2

−20x−16

⇒−4f(x)=−12x

2

+20x+16

Answer 2

Answer:

I hope this is how it's done.

good luck with your study ❤️
