X f(x) = x2 + 4x . x2_4

PtichkaEL [24]

The answer is 1/(x+4)
Explanation:
You would factor out the denominator
So,
(X-4)(x+4)=x^2-16
So, x-4/(x+4)(x-4)
Then x-4 cancels each other out from the numerator and denominator
Leaving 1/x+4

HELP pleaseee ASAP I’m stuck

Blizzard [7]

Step-by-step explanation:

using trig, tangent is equal to opposite over adjacent.

in this case, the angle is 45, opposite is 7, and adjacent is a.

thus tan 45° = 7/a

solve for a to get a = 7/tan 45° = 4.32

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.
