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.

its an acute right triangle

step-by-step explanation:

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
