Answer:

Option C is the answer.

Step-by-step explanation:

Graph represented by y = (x + 2)² is a quadratic function or a parabola.

This equation is in the vertex form y = (x -h)² + k

where (h, k) is the vertex.

So in the graph y = (x + 2)², vertex is (-2, 0)

Now the translated form of the parabola is y = x² + 3

In this equation vertex is (0, -3)

We can now easily find the translation of vertex (-2, 0) to (0, 3)

Horizontal shift = 0 - (-2) = +2

Vertical shift = 3 - 0 = +3

Therefore, a horizontal shift of 2 units right and vertical shift of 3 units up has been done in the parent function.

Option C. is the answer.

What is the value of the expression below when x = 3?<br> 10x2 – 7x + 10
QveST [7]

Answer:

79

Step-by-step explanation:

To find the value of 10x^2 – 7x + 10, when x = 3, simply plug in the value of x in the expression and solve as follows:

10(3)^2 – 7(3) + 10

10(9) – 21 + 10

90 – 21 + 10

79

The value of 10x^2 – 7x + 10, when x = 3, is 79

The formula for the surface area of a circular cylinder is SA = 2πr 2 + 2πrh cubic units. What do 2πr 2 and 2πrh represent?
Molodets [167]
Remember
area=pir^2
circumference=2pir

the surface aera if you thinkg about it is
2 times the tops+area around

the tops are circles so 2*pir^2 is tops

the area around is a rectangle that has been wrapped around the cylinder,
the hieght is the legnth and the circumference is width
so 2hpir is the area around

2pir^2 is the areas of the tops
2hpir is the area around

Declan has n baseball cards. Sam has 4 times as many baseball cards as Declan. Amaya has 7 fewer baseball cards than Sam. Which
Kamila [148]

Answer:

4n-7

Step-by-step explanation:

First, you know that Sam's equation is 4n, since it is 4 times Declan's value n. Next, you take Sam's equation and subtract 7 from that value, since Amaya has 7 fewer cards than Sam. The final equation will be 4n-7.
