Answer:

c + ab

Step-by-step explanation:

The way an expression is written is the given you have presented to us.

The commutative law of addition would turn it around as

Find the derivative of the function using the definition of derivative.f(x) = mx + qf '(x) =

Natasha_Volkova [10]

Answer:

a) $f'(x) = m$

b) $x \in (-\infty, \infty)$

c) $x \in (-\infty, \infty)$

Step-by-step explanation:

We are given the following in the question:

$f(x) = mx + q$

a) We have to find the derivative of the given function.

$f'(x) = \dfrac{f(x+h)-f(x)}{h}\\\\= \dfrac{m(x+h)+q - mx - q}{h}\\\\f'(x) = \dfrac{mh}{h}\\\\f'(x) = m$

b) Domain of f(x)

Domain is the collection of all values of x for which the function is defined.

Domain of f(x) is all real numbers.

$x \in (-\infty, \infty)$

c) Domain of f'(x)

Domain of f'(x) is all real numbers.

$x \in (-\infty, \infty)$

Which equation is parallel to y−4 = 2(x+1) and goes through the point (-2, -14)?

Anna71 [15]

Answer:

Step-by-step explanation:

y - 4 = 2x + 2

y = 2x - 6

y + 14 = 2(x + 2)

y + 14 = 2x + 4

y = 2x - 10

the solution is c
