A (1)= -5×3(1)-1

a(1)= -5×3-1

a (1)= -16

A(4)= -5×3(4)-1

a (4)= -5×12-1

a( 4) = -60-1

a(4)= -61

A(8)= -5×3(8)-1

a(8)= -5×24-1

a(8)= -120-1

a(8)= -121

verbally explain how to obtain the graph of the quadratic function f(x)=-2(x+3)^2-4 from the graph of y=x^2.
Ksivusya [100]

Answer:

The graph f(x)=-2(x+3)^2-4 is a reflection over the x-axis, vertical stretch by a factor of 2, a horizontal translation left 3 units and a vertical translation 4 units down of the graph y=x^2.

Step-by-step explanation:

The graph f(x) is reflected over the x-axis because the negative is outside of the parenthesis.

it's a vertical stretch by a factor of 2 because 2 is outside of the parenthesis and is greater than 1.

(x+3) is a horizontal translation left 3 units because it is inside the parenthesis.

-4 is vertical translation 4 units down because it is outside of the parenthesis.
