Can someone me find these anwsers?

Answer 1.a):

x-intercept= (2,0)

Because graph crosses x-axis at x=2

Answer 1.b):

y-intercept= (0,4)

Because graph crosses y-axis at y=4

Answer 1.c):

Domain= All real numbers.

Because graph covers all x-values along x-axis when checking from left side to right side.

Answer 1.d):

Range = All real numbers.

Because graph covers all y-values along y-axis when checking from bottom side to up side.

Answer 1.e):

Minimum = NO

Answer 1.f):

Maximum = NO

Answer 1.g):

Increasing Interval = NO

Because graph goes all the time downward.

Answer 1.f):

Decreasing Interval = (-infinity, infinity)

Because graph goes all the time downward when looking from -infinity to infinity.

Same way we can solve other problems.

Answer 2.a):

x-intercept= (-1,0), (2,0)

Answer 2.b):

y-intercept= (0,-2)

Answer 2.c):

Domain= All real numbers.

Answer 2.d):

Range = [-2.25, infinity)

Answer 2.e):

Minimum = -2.25

Answer 2.f):

Maximum = NO

Answer 2.g):

Increasing Interval = (0.5, infinity)

Answer 2.f):

Decreasing Interval = (-infinity, 0.5)

Answer 3.a):

x-intercept= (-2,0)

Answer 3.b):

y-intercept= (0,-6)

Answer 3.c):

Domain= All real numbers.

Answer 3.d):

Range = (-infinity, 2)

Answer 3.e):

Minimum = NO

Answer 3.f):

Maximum = NO

Answer 3.g):

Increasing Interval = NO

Answer 3.f):

Decreasing Interval = (-infinity, infinity)

Answer 4.a):

x-intercept= (-4,0), (2,0)

Answer 4.b):

y-intercept= (0,-2)

Answer 4.c):

Domain= All real numbers.

Answer 4.d):

Range = (-3,infinity)

Answer 4.e):

Minimum = -3

Answer 4.f):

Maximum = NO

Answer 4.g):

Increasing Interval = (-1, infinity)

Answer 4.f):

Decreasing Interval = (-infinity, -1)

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

i agree because i see the other persons thinking is clear
