The pH is calculated with the formula pH = - log [H3O+], where [H3O+]  is the concentration of H3O+

=> [H3O+] = 5.6 * 10^ -7.

=> pH = - log (5.6 * 10 ^-7) = 6.25

That is a slightly acid pH, because pH is in the range 0 to 14, and 7 is neutral.

pH = 6.25

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
