HEL M PPEOP The graph of function `f\left(x\right)=-x^{2}+2x+3` is shown on the left. Select all statements that are true.

1.The vertex is at the maximum.
2.The vertex form of the function is f(x)=-(x+1)^2+4
3.The function is positive over the interval -1 1
5.As x approaches positive infinity, the function f(x) decreases.

i think this could be a possible answer (1 / 84) -1

good luck! : d

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

hope this !

let me know
