Unfortunately, the browser used by Answers.com for posting questions is incapable of accepting mathematical symbols. This means that we cannot see the mathematically critical parts of the question. We are, therefore unable to determine what exactly the question is about and so cannot give a proper answer to your question.
In this question, for example, it is not clear whether the characters immediately after "log" are the bases. Also, it is unclear whether the first "term" is log(3-x) or log(3)-x: both logs to base 4.

What is the derivative of 3x?
Let y = 3x y' = 3(x)' y' = 3(x1)' y' = 3[1x(1-1)] y' = 3(1x0) y' = 3(1 x 1) y' = 3 In general: y = xn y' nx(n-1)

X plus one over x squared plus two?
it equals x1 it equals x1
What is the definition of a point-slope form?
point slope form is y-y1=m(x-x1). x1 and y1 are both points and m is the slope.
State and prove Fundamental theorem of integral calculus?
This part is sometimes referred to as the First Fundamental Theorem of Calculus.Let f be a continuous real-valued function defined on a closed interval [a, b]. Let F be the function defined, for all x in [a, b], byThen, F is continuous on [a, b], differentiable on the open interval (a, b), andfor all x in (a, b).ProofFor a given f(t), define the function F(x) asFor any two numbers x1 and x1 + Δx in [a, b], we haveandSubtracting the two equations givesIt can be shown that (The sum of the areas of two adjacent regions is equal to the area of both regions combined.)Manipulating this equation givesSubstituting the above into (1) results inAccording to the mean value theorem for integration, there exists a c in [x1, x1 + Δx] such thatSubstituting the above into (2) we getDividing both sides by Δx gives Notice that the expression on the left side of the equation is Newton's difference quotient for F at x1.Take the limit as Δx → 0 on both sides of the equation.The expression on the left side of the equation is the definition of the derivative of F at x1.To find the other limit, we will use the squeeze theorem. The number c is in the interval [x1, x1 + Δx], so x1 ≤ c ≤ x1 + Δx.Also, andTherefore, according to the squeeze theorem,Substituting into (3), we getThe function f is continuous at c, so the limit can be taken inside the function. Therefore, we get which completes the proof.
How do you simplify 3x-4x plus 9x-x?
Right, 3x-4x+9x-x1. 3x - x = 2x2. 9x-4x = 5x- 2x +5x = 7x
How do you solve for slope from two points and a graph?
Points: (x1, y1) and (x2, y2) Slope: y1-y2/x1-x2
What is the equation of a line that passes through (78) and has a slope of -3?

How do you solve a cubic?
Although there are formal methods, the simplest is to see if the cubic can be factorised. If so, you'll have a linear factor and a quadratic, both of which are easy to solve. Alternatively, you could try solving it graphically. Another possibility is to solve it numerically. The derivative of a cubic, of the form f(x) = ax3 + bx2 + cx + d is f'(x) = 3ax2 + 2bx + c. Make an initial estimate x1. An improved estimate is x2 = x1 - f(x1)/f'(x1). Use x2 to make next estimate, and so on.
What is 3x times x squared?
(3x)(x2) = 3x3.Think of this as (3x1)(1x2). First multiply the numbers: (3)(1) = 3. next multiply the variables: (x1)(x2) = x1+2 = x3 (when you multiply powers with the same base, add the exponents)
Explain how do you write an equation of a line in standard form when two points on the line are given?
Th e two points are X1,Y1 and X2, Y2 slope, m, is y2-y1 divided by x2-x1 then standard form is y = mx +b plug in y2 for y and x2 for x and solve b or plug in y1 for y and x1 for x and solve b
How do you differentiate y equals 6 sqrtx minus 3x?
y = 6*x1/2 - 3x dy/dx = 6*(1/2)*x-1/2 - 3 = 3x-1/2 - 3 = 3/sqrt(x) - 3 or 3[1/sqrt(x) - 1]

How do you find a gradient of a line without a graph?
Select two values of x: (x1 and x2) within the domain. Solve the equation of the line to find the corresponding values for y: (y1 and y2). Then the gradient = (y1 - y2) / (x1 - x2)
What are the coordinates of the y-intercept of the line represented by the equation 3x-4y equals 40?
