Given the parent function f(x) = x², define the function g(x) that
Bas_tet [7]

Answer:

Part 1) g(x)=-x^{2}

Part 2) g(x)=(x+3)^{2}

Part 3) g(x)=x^{2}+7

Step-by-step explanation:

we have

The parent  function is f(x)=x^{2}

This is a vertical parabola open upward with vertex at origin (0,0)

Part 1) Reflection over the x-axis

The rule of the reflection across the x=axis is equal to

(x,y) ------> (x,-y)

so

f(x) -----> g(x)

The function g(x) will be

g(x)=-x^{2}

Part 2) Horizontal shift left 3 units

The rule of the translation is

(x,y) ------> (x-3,-y)

so

f(x) -----> g(x)

The function g(x) will be

g(x)=(x+3)^{2}

Part 3) Vertical shift up 7 units

The rule of the translation is

(x,y) ------> (x,y+7)

so

f(x) -----> g(x)

The function g(x) will be

g(x)=x^{2}+7

Which expression represents triple the sum of y + 2? A.) 3(y + 2) B.) 5y C.) 3y +2 D.) 6
Harlamova29_29 [7]

Answer:

A. 3(y+2)

Step-by-step explanation:

B wouldn't work because it would be safe to assume that it represents the quintuple of the sum.  C also wouldn't work because although the y is tripled, the 2 isn't.  And D wouldn't work because it is only tripling 2.

A should be your answer since you are distributing the number 3 which is the same thing as a triple to get the sum of the answer which is 3y + 6.

If you flipped the coin 100 times, how many heads would you expect to get? Explain your answer.
Irina18 [472]

Answer:

You would expect to get 50 heads

Step-by-step explanation:

Each time you flip a coin you will either get heads or tails. This means that you have a 1/2 probability of getting heads. If you use this then you need to multiply 1/2 and 100 to get the expected amount of heads. Multiplying by a half is just dividing by 2. Therefore, the answer is 100/2 = 50. The answer is 50 heads
