If f(x)=3x squared -2x + 1 what is f(x-2)

Mathematics
1 answer:
meriva3 years ago
5 0

Answer:

f(x-2) = 3x^2 - 14x + 17

Step-by-step explanation:

All you have to do is put (x-2) for every x:

3(x-2)^2 - 2(x-2) + 1

Make sure you FOIL (x-2)^2 first:

x^2 - 4x + 4

Now distribute the 3:

3x^2 - 12x + 12

Now distribute the 2 in the 2(x-2):

3x^2 - 12x + 12 - 2x + 4 + 1

Combine like terms:

3x^2 - 14x + 17 = f(x-2)

Hope that helps!

Answer:

P = -10

5p - 8(p + 1) > 16

5(-10) - 8(-10 + 1) > 16

-50 - 8(-9) > 16

-50 + 72 > 16

22 > 16

Rewrite in simplest rational exponent form √x • 4√x. Show each step of your process.
Vikentia [17]

Step-by-step explanation:

=  \sqrt{x} .4 \sqrt{x}

=  {x}^{ \frac{1}{2} }  \times 4 {x}^{ \frac{1}{2} }

= 4 {x}^{ \frac{1}{2} +  \frac{1}{2}  }

= 4 {x}^{ \frac{2}{2} }

= 4 {x}^{1}

= 4x

Which graph represents the function f(x) = |x + 3|?
Sophie [7]
Answer: (B)
Explanation: If you are unsure about where to start, you could always plot some numbers down until you see a general pattern.

But a more intuitive way is to determine what happens during each transformation.
A regular y = |x| will have its vertex at the origin, because nothing is changed for a y = |x| graph. We have a ray that is reflected at the origin about the y-axis.

Now, let's explore the different transformations for an absolute value graph by taking a y = |x + h| graph.
What happens to the graph?
Well, we have shifted the graph -h units, just like a normal trigonometric, linear, or even parabolic graph. That is, we have shifted the graph h units to its negative side (to the left).

What about the y = |x| + h graph?
Well, like a parabola, we shift it h units upwards, and if h is negative, we shift it h units downwards.

So, if you understand what each transformation does, then you would be able to identify the changes in the shape's location.

I’m not entirely sure how to answer this without a word problem, but from what I see, all you have to do is multiply the two numbers.
12 x 43= 516
5 x 88 = 440
8x 63= 504
7 x 28= 196
Usually, when you see a number followed by another number in parentheses, like here, that means to multiply.
