2. what is the y intercept of the quadratic function f(x) =6x^2-3x+1 (
1 point)

a -3
b. 1/4
c. 1
d. 6

3. what is the axis of the symmetry of the quadratic function f(x) =4(x+9)^2-5 (1 point)

a. x=-9
b. x=9
c. x=-5
d. x=5

4. rewrite f(x)=3x^2 +6x-72 in factored form. (1 point)

a. f(x)=3(x-6)(x+4)
b. f(x)=3(x+6)(x-4)
c. f(x)=3(x-8)(x+3)
d. f(x)=3(x+8)(x-3)

5. rewrite f(x)=-2x^2+16x-11 in vertex form. (1 point)

a. f(x)=-2(x+4)^2+5
b. f(x)=-2(x-4)^2+5
c. f(x)=-2(x+4)^2+21
d. f(x)=-2(x-4)^2+21

2.C

3.B

4.B

5.D

Step-by-step explanation:

2. the y intercept in this equation is the c value, which is 1 so the answer is c

3. The vertex of this function would be (9, -5) and the axis of symmetry is the first value so its 9, B

4. Not that hard, tip is to just distribute in all the answers and see which one gives you the original equation, it is B

5. You solve the original equation by completing the square, if you don't know how to do that look it up. Answer is D

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
