What transformations change the graph of f(x) to the graph of g(x)?
Dennis_Churaev [7]

For this case we have that the main function is given by:

f (x) = - 7x ^ 2

We apply the following transformations:

Vertical expansions:

To graph y = a * f (x)

If a> 1, the graph of y = f (x) is expanded vertically by a factor a.

For a = 5 we have:

h (x) = 5 * f (x)\\h (x) = 5 * (- 7x ^ 2)\\h (x) = - 35x ^ 2

Vertical translations:

Suppose that k> 0

To graph y = f (x) + k, move the graph of k units up.

For k = 5 we have:

g (x) = h (x) + k\\g (x) = - 35x ^ 2 + 5

Answer:

The graph of g (x) is the graph of f (x) stretched vertically by a factor of 5 and translated up 5 units.

Can someone help me with 4-6 plz
satela [25.4K]

Step-by-step explanation:

4. To use SSS, you need three pairs of congruent sides.  You're given two pairs of congruent sides, so the additional information needed is WY ≅ KM.

5. To use ASA, you need a pair of congruent sides between two pairs of congruent angles.  You're given one pair of congruent angles, and since the triangles share a common side, we know BC ≅ BC.  So the additional information needed is ∠WBC ≅ ∠ACB.

6. To use SAS, you need a pair of congruent angles between two pairs of congruent sides.  You're given two pairs of congruent sides, so the additional information needed is ∠I ≅ ∠F.
