What is the vertex form of the equation of the parabola with a focus at (8,7) and a directrix of #y=18 #? What is the vertex form of the equation of the parabola with a focus at (12,22) and a …
Domain and Range of a Function - Algebra - Socratic
Then the range of #f(x)# is the set of values of #f(x)# over #D#. We can think of this as the valid outputs. To determine the domain and range of a function, first determine the set of values for …

A sequence is defined by the recursive formula f (n + 1) = f(n ...
2018年6月27日 · The formula states that the next term in the sequence is generated by subtracting two from the previous one. We know that the first term is #18#, so we have. …
If f(3)=13, f' is continuous, and the integral from 3 to 5 f ... - Socratic
2016年2月26日 · f(5) = 37 See explanation below. Since AA x, f'(x) = f'(x), f is a primitive function of f'. Therefore, int_3^5 f'(x) dx = f(x) |_3^5 = f(5) - f(3) = f(5) - 13 = 24 by the fundamental …
Amplitude, Period and Frequency - Trigonometry - Socratic
Frequency and period are related inversely. A period P is related to the frequency f. P = 1/f. Something that repeats once per second has a period of 1 s. It also have a frequency of 1/s. …
Factoring Completely - Algebra - Socratic
For factoring polynomials, "factoring" (or "factoring completely") is always done using some set of numbers as possible coefficient. We say we are factoring "over" the set. #x^3 -x^2-5x+5# can …
Direct Variation - Algebra - Socratic
When you have a direct variation, we say that as your variable changes, the resulting value changes in the same and proportional manner. A direct variation between y and x is typically …
If f is continuous and (0,4)∫ f(x) dx = -18, how to evaluate (0,2)∫ f ...
2015年9月15日 · Explanation: Assuming that you mean that. ∫ 4 0 f (x)dx = − 18. and you want to evaluate ∫ 2 0 f (2x)dx. set u = 2x hence du = 2dx and. ∫ 2 0 f (x)dx = ∫ 4 0 (1 2) ⋅ f (u)du = (1 2) …
Suppose f varies inversely with g and that f = 45 when g = 6
2016年5月31日 · 30 Given fprop 1/g or f_1 .g_1=f_2 .g_2 .....(1) Let the required value of f=x Inserting in equation (1 ...
