Which function corresponds to the table of inputs and outputs?

Anarel [89]

Answer:

f(x) = 3x + 2

Step-by-step explanation:

That's easy to find out. You have your input number, which is your x value, and you have your output number which is your y value (or f(x)).

All you have to do is see if each of the proposed answer works for ALL entries in the data set.

f(x) = 3x + 2

for x = 3 ===> 11 = 3 (3) + 2 = 11 YES

for x = 5 ===> 17 = 3 (5) + 2 = 17 YES

for x = 7 ===> 23 = 3 (7) + 2 = 23 YES

for x = 9 ===> 29 = 3 (9) + 2 = 29 YES

f(x) = 2x + 5

for x = 3 ===> 11 = 2 (3) + 5 = 11 YES

for x = 5 ===> 17 = 2 (5) + 5 = 15 NO - we stop here for this function

f(x) = x + 7

for x = 3 ===> 11 = (3) + 7 = 10 NO - we stop here for this function

f(x) = 3x + 1

for x = 3 ===> 11 = 3 (3) + 1 = 10 NO - we stop here for this function

Which transformation will map an isosceles trapezoid onto itself? rotation by 180° about its center, reflection across a diagona

alukav5142 [94]

Answer:

The correct option is 4.

Step-by-step explanation:

The non parallel sides of an isosceles trapezoid are congruent.

The image of an isosceles trapezoid is same as the preimage of isosceles trapezoid if

1. Reflection across a line joining the midpoints of parallel sides.

2. Rotation by 360° about its center.

3. Rotation by 360° about origin.

If we rotate the trapezoid by 180° about its center, then the parallel sides will interchanged.

If we reflect the trapezoid across a diagonal, then the resultant figure will be a parallelogram.

If we reflect across a line joining the midpoints of the nonparallel sides, then the parallel sides will interchanged.

After rotation by 360° about the center, we always get an onto figure.

Therefore option 4 is correct.

GREYUIT [131]

Answer:

D

Step-by-step explanation:

the picture is extremely diffuse and out of focus.

but I think I understood the content.

first the easiest part : the straight line on the right side of the graph.

we see the y increases exactly like the x. so, x increases by 2, then y increases by 2 too.

therefore the slope is 1 (y change / x change), and the function is simply y = x

and the line only starts with x=2 and goes on for all x greater than 2.

just for that alone it can be only D, because all the other answer options violate that behavior.

and the left part of the function must confirms this.

first of all, it has to be for x < 2 (again, only D).

and I found |-x²| really funny. this is the same as simply x², as a squared number can only be positive. so, making it negative and then taking the absolute value of that result creates the same original positive number again.

and x² can't be the function, because that would be a parabola that starts at the origin (0, 0), and then curves up left and right from there.

so, this can't be our function in the graph.

again, D is the the only fitting answer.
