Answer:

g(3) = 34

Step-by-step explanation:

To evaluate g(3) substitute x = 3 into g(x), that is

g(3) = 4(3)² - 3(3) + 7 = (4 × 9) - 9 + 7 = 36 - 9 + 7 = 34

Answer:

$\displaystyle f'(x) = \frac{4}{x^2}$

General Formulas and Concepts:

Calculus

Limits

Limit Rule [Variable Direct Substitution]: $\displaystyle \lim_{x \to c} x = c$

Differentiation

Derivatives
Derivative Notation

The definition of a derivative is the slope of the tangent line: $\displaystyle f'(x) = \lim_{h \to 0} \frac{f(x + h) - f(x)}{h}$

Step-by-step explanation:

Step 1: Define

Identify.

$\displaystyle f(x) = -\frac{4}{x}$

Step 2: Differentiate

[Function] Substitute in x: $\displaystyle f(x + h) = -\frac{4}{x + h}$
Substitute in functions [Definition of a Derivative]: $\displaystyle f'(x) = \lim_{h \to 0} \frac{-\frac{4}{x + h} - \big( -\frac{4}{x} \big)}{h}$
Simplify: $\displaystyle f'(x) = \lim_{h \to 0} \frac{4}{x(x+ h)}$
Evaluate limit [Limit Rule - Variable Direct Substitution]: $\displaystyle f'(x) = \frac{4}{x(x+ 0)}$
Simplify: $\displaystyle f'(x) = \frac{4}{x^2}$

∴ the derivative of the given function will be equal to 4 divided by x².

What are the coordinates of the midpoint of the segment whose endpoints are A (-1, -2) and B (6, 12)

Klio2033 [76]

Answer:

Mid point = $(\frac{5}{2} ,5)$

Step-by-step explanation:

We are given the coordinates of the end points of a line segment AB and we are to find the coordinates of its mid point.

The coordinates of the end points are: A (-1, -2) and B (6, 12).

We know the formula of the mid point:

Mid point = $(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )$

So putting in the given values to find the mid point of line segment AB:

Mid point = $(\frac{-1+6}{2} ,\frac{-2+12}{2} )$ = $(\frac{5}{2} ,5)$

The graph shows a proportional relationship between the distance a car travels and the fuel it consumes.

statuscvo [17]

Answer:

2.5

Step-by-step explanation:

if you take 80 and 120 on the graph look at the middle you get 100 and in between 2 and 3 you get 2.5 so it would take 2.5 gallons of gas for 100 miles
