Given the function f(x)=(x+3)2-1, which of the following would describe a shift of the vertex 3 units to the left.
A. f(x + 3)
B. f(x)+3
C. f(x)-3
D. f(x-3)
Answers
Answer:
A. f(x+3)
Step-by-step explanation:
The vertex form is y=a(x-h)^2+k. To move left, your 'h' value has to be negative, so in this case, it'd be -3, but wait. Since it already tells you to subtract the 'h' value, subtracting -3, (-(-3), would be the same as adding 3. So inside the form, it has to be (x+3) to make sense. A is the correct answer.
B is incorrect because that just shifts the function 3 units up.
C is incorrect because that shifts the function 3 units down.
D is incorrect because that shifts the function 3 units right.

Tyra solved the quadratic equation x2-10x -24 = 0by factoring. Her work is shown below:
Step 1: x2-10x -24 = 0
Step 2: x2-4x - 6x - 24 = 0
Step 3: (x2-4x) + (-6x - 24) = 0
Step 4: x(x-4) - 6(x - 4)=0
Step 5: (x-4)(x-6)=0
Step 6: x-4 = 0, x-6 = 0
Step 7: x=4 or x = 6
Step 8: 4, 6

3.Suppose a car is traveling northeast on King Avenue and turns right onto 3rd Street. What is the measure of the angle created by the car's turning?
Answers
Answer:
4th street
Step-by-step explanation:
Sorry but I only have an anwser for the first one
The measure of the angle created by the car's turning is 105°
Step-by-step explanation:
Given : a car is traveling east on 4th Street and turns onto King Avenue heading northeast.
We have to calculate the measure of the angle created by the car's turning.
Since, car is travelling in east direction on 4th street that is from A to D as shown below in image by arrow.
Then at point B, the car turns toward King Avenue heading northeast. that is B to C as shown below in image
Since, we need to calculate the measure of the angle created by the car's turning that is measure of ∠ABC.
AD is a straight line, thus measure of any angle at line segment AD is 180° as angles on one side of a straight line always add to 180 degrees
Therefore, at B,
∠ABC + ∠CBD = 180°
Aldo given , ∠CBD = 75°
Thus, the measure of ∠ABC is ,
⇒ ∠ABC = 180° -∠CBD
⇒ ∠ABC = 180° - 75°
⇒ ∠ABC = 105°
Thus, the measure of the angle created by the car's turning is 105°
