对f(x+h)在x处展开，就有你要的答案了。只是你理解的是在定点展开，这里的x是动点罢了（你可以把动点x看做在区间内随意 ...

2017年5月7日 · x^3+3hx^2+3h^2x+h^3 "one way is to expand using the result" (x+a)(x+b)(x+c) =x^3+(a+b+c)x^2+(ab+bc+ac)x+abc "here " a=b=c=h rArr(x+h)^3 =x^3+(h+h+h)x^2+(h^2+h^2+h^2)x+h.h.h =x^3+3hx^2+3h^2x+h^3

2015年6月17日 · (x+h)(x+h) = F + O + I + L = (x*x) + (x*h) + (h*x) + (h*h) =x^2 + 2hx + h^2 FOIL is a useful mnemonic to help you remember all the combinations to multiply when multiplying two binomials. In addition, if the binomials are both in standard order, then FOIL tends to group the terms in a helpful way. To multiply (x+h)(x+h) add together each of the products: First : x*x = x^2 Outside : x*h = hx ...

x的发音部位和k,g是一样的。h的发音部位靠后得多，在声门位置。后者类似你自然状态下发笑的「哈哈」声。 另外，相当一部分人的普通话里，那个汉语拼音写为h的声母的实际读音并不是[x]，很多南方人发的是[h]，北方人发的是小舌擦音[χ]

2016年6月14日 · No. They have no special significance. All of these are simply used by convention to refer to a function. For example, f(x)=e^x, a(x)=e^x, and z(x)=e^x all mean the same thing. However, some notations mean only one thing. For example, zeta(s) refers to the Riemann zeta function: sum_(n=1)^oo1/n^s (See this link for more info: Riemann zeta function) In general, though, functions that describe ...

2016年8月6日 · To find f(x+h) substitute x = x + h into the function. #f(color(red)(x+h))=(color(red)(x+h))^2-2(color(red)(x+h))+5#

Question 482915: Expand (x+h)^3 Found 2 solutions by rfer, richard1234: Answer by rfer(16322) (Show Source):

2017年12月21日 · Please see below. General equation of parabola is of the form y=a(x-h)^2+k or x=a(y-k)^2+h. Former is known as verticle parabola and latter is known as horizontal parabola. In both cases vertex is (h,k), axis of symmetery is x-h=0 in former case and y-k=0 in latter case. Focii are (h,k+1/(4a)) in former case and (h+1/(4a),k) in latter case. Directrix is y=k-1/(4a) in former case and x=h-1/(4a ...

Use the table with two columns #color(red)(x and y# to draw the graph as shown below: The Parent Graph of #color(red)(y=x^2# can also be seen for comparison, to better understand transformation. Also note that, Axis of Symmetry is #color(red)(x=h# #rArr x= 3# We can verify this from the graph below: Hope it helps.
