Answer:

f(-1)=2

f(1)=6

f(2)=11

Step-by-step explanation:

The given function is f(x)=2x^3-3x^2+7

Substitute x = -1 to find the value of f(-1)

f(-1)=2(-1)^3-3(-1)^2+7\\\\=-2-3+7\\\\=2

Thus, f(-1)=2

Substitute x = 1 to find the value of f(1)

f(1)=2(1)^3-3(1)^2+7\\\\=2-3+7\\\\=6

Thus, f(1)=6

Substitute x = 2 to find the value of f(2)

f(2)=2(2)^3-3(2)^2+7\\\\=16-12+7\\\\=11

Thus, f(2)=11

Answer:

Step-by-step explanation:

The value of the function f(x) at x=a can be determined by substituting a instead of x into the function expression.

1. When x=-1, then

f(-1)=2\cdot (-1)^3-3\cdot (-1)^2+7=-2-3+7=2.

2. When x=1, then

f(1)=2\cdot 1^3-3\cdot 1^2+7=2-3+7=6.

3. When x=2, then

f(-1)=2\cdot 2^3-3\cdot 2^2+7=16-12+7=11.

Determine the number of outcomes in the event. Decide whether the event is a simple event or not. You randomly select one card f
Marat540 [252]

Answer:

No we can consider A as single event. See the explanation below

Step-by-step explanation:

Let's define the event A as:

A=" Select a 4 from a standard deck of 52 cards"

We know that in a standard deck we have 4 different types of 4, spade, heart, diamond and club.

And by definition of simple event we need to have just one possible outcome in the experiment, and on this case we have 4 possible options for event A, so for this reason the event A can't be considered as simpl event.

You're given a table of x values and an equation. To solve, plug in the values for x.

First box: y=2(-3)-1=-7
Second box: y=2(-2)-1=-5.

See if you can solve the third one.
