Question

if f(x+2)=2x²-3x+5 then find f(1)​

Answer 1

Step-by-step explanation:

The given function is

f(x — 2)=2x²+3x — 5

Put x — 2 = z

Then x= z +2

This gives

f(z)= 2(z +2)²+3(z +2) — 5

f(z)=2(z²+4z +4)+3z +6 — 5

f(z)=2z² + 8z + 8 + 3z + 1

f(z)=2z² + 11z + 9

If we change the variable to x we get

f(x)=2x² + 11x + 9
