Answer:

For x < -3 or 3.438 > 3 the exponential function exceeds the polynomial function.

Step-by-step explanation:

The given functions are

f(x)=3(4)^(2x-4)

h(x)=(x+2)^3+1

In the given functions f(x) is an exponential function and h(x) is polynomial.

We need to find the x-value in which the exponential function exceeds the polynomial function.

The table of values is shown below,

x            f(x)                    h(x)

-4        1.8×10⁻⁷              -7                   f(x)>h(x)

-3            0                      0                   f(x)=h(x)

-2         4.6×10⁻⁵             1                    f(x)<h(x)

0          0.0012                9                   f(x)<h(x)

2              3                     65                 f(x)<h(x)

3.438       161.845          161.845           f(x)=h(x)

4             768                 217                 h(x)>f(x)

From the above table it is clear that for x < -3 or 3.438 > 3 the exponential function exceeds the polynomial function.

2x + y = -8<br> 3x - 5y = -25
Margarita [4]

Answer:

x=-5, y=2. (-5, 2).

Step-by-step explanation:

2x+y=-8

3x-5y=-25

------------------

5(2x+y)=5(-8)

3x-5y=-25

-------------------

10x+5y=-40

3x-5y=-25

--------------------

13x=-65

x=-65/13

x=-5

2(-5)+y=-8

-10+y=-8

y=-8-(-10)=-8+10=2

bonufazy [111]

Answer:

Step-by-step explanation:

I. { (22,22) , (22,23) , (22,24) , (23,22) , (23,23) , (23,24) }

Reflexive : True because we see the pairs (22,22) , (23,23)..

Symmetrix : NO, as we see the pairs (22,24) BUT NOT (24,22)

Transitive : YES, As we see (22,22 ) and (22, 24) , we see the pairs (22,24)

Antisymmetric : NO

II){ (21,21) , (21,22) , (22,21) , (22,22) , (23,23) , (24,24) }

Reflexive : True because we see the pairs (22,22) , (23,23) (21,21)

Symmetrix : Yes, as we see the pairs (21,22) AND (22,21)

Transitive : YES,

Antisymmetric : NO
