E^x not equal to zero
Zina [86]

Answer:

e^x \neq 0

Step-by-step explanation:

We will prove this with the help of a contradiction:

Let as assume that e^x = 0

Multiplying both sides by e^{-x}

e^x\times e^{-x} = 0\times e^{-x}\\e^0 = 0\\1 = 0

which is not possible.

Hence, our assumption was wrong which led us to a contradiction.

Thus,

e^x \neq 0

Simplify (y x y^1/3)^3/2
jok3333 [9.3K]

Answer:

y^2

Step-by-step explanation:

(y x y^1/3)^3/2 would be clearer if written as

(y*y^(1/3))^(3/2).

Because y^a*y^b = y^(a + b), the quantity inside the first set of parentheses becomes

y^(4/3)

and if we apply the power (3/2) to this result, we get:

                                 4       3

(y^(4/3))^(3/2) = y^{ ----- * ----- ) = y^2

                                 3       2

Let f(x) = -2x2 and g(x) = 2x – 4. Using your graphing calculator,
Monica [59]

Answer:

1 and -2

Step-by-step explanation:

-2x^2=2x-4   so 2x^2 + 2x -4 = 0

2(x^2+x-2)=0

x^2+x-2  =  (x-1)(x+2)

x=1 x=-2

If the graph of the function g defined by g(x)=-2x^2+9. Is translated vertically downward by 8 units, it becomes the graph of a
tester [92]
G ( x ) = - 2 x² + 9
If this function is translated vertically downward by 8 units it becomes:
f ( x ) = g ( x ) - 8
f ( x ) = - 2 x² + 9 - 8
Answer:
f ( x ) = - 2 x² + 1
