Question

F (x) = – x2 + 4x + 1

Answer 1

Answer:

The 2 solutions are 0 and 3,

Step-by-step explanation:

– x2 + 4x + 1 = x + 1

-x^2 + 3x = 0

x(-x - 3)

x = 0 or -x - 3 = 0  which gives x = 3.

Answer 2

Answer:

x = 0 or x = 3

Step-by-step explanation:

if f(x) = g(x) then – x2 + 4x + 1 = x + 1

add the like terms

-x^2 +3x = 0

-x (x-3) = 0 then x is either 0 or 3
