What are the solutions to the equation f(x)= g(x)?

PIT_PIT [208]

Answer:

2 solutions

Step-by-step explanation:

We are given the equations of f(x) and g(x).

To find f(x) = g(x), we just let those two equations equal each other

$x^{2} -4x+5=x+1$

Group all like terms,

$x^{2} -3x+4=0$

Factorise,

$(x-4)(x+1)=0$

$x=4, x=-1$

Therefore, there are two solutions

Hope this helped!!
