Can anyone help me with a CALC problem

A) The function f+g is just the sum of the 2 functions f and g.
     The derivative of f+g is also just the sum of the derivatives.

So to find slope of new tangent line, you find sum of the slopes for f and g.
---> m = 2+2 = 4

The point on new curve is (4, f(4)+g(4))  -----> (4,17)

The equation of tangent line is then:
y - 17 = 4(x -4)
y = 4x + 1


b) and c) are done the same way. f-g means subtract slopes.
2f means double slope etc...

Answer:

D

Step-by-step explanation:

Remember how absolute values turn everything inside of it into a positive number? Like |-4|=4 and |4|=4 as well.

Well, it works the same for equations.

When you have an absolute value equation like this, you have to split it into two parts.

The positive version

| d-3.5 | ≤ 1.5

and the negative version

|-(d-3.5)| ≤ 1.5

solve for the value of d in both equation.

<em>Remember that you have to flip the inequality sign when dividing or multiplying by a negative number</em>

I assume you know how to graph the inequality once you get the value for d.

d≤5 and d≥2

so

2 ≤ d ≤ 5

meaning d is between 2 and 5.
