2016年10月16日 · What does #f(x)=y# mean? How do you write the total cost of oranges in function notation, if each orange cost $3? How do you rewrite #s=2t+6# in function notation?

2017年1月14日 · The answer is =16 This is a composition of functions f(x)=x+1 g(x)=3x-2 g(f(x))=g(x+1)=3(x+1)-2 =3x+3-2=3x+1 Therefore, g(f(5))=3*5+1=15+1=16

2016年2月17日 · f = (5-g)/7 >to isolate the term with f in it , firstly subtract g from both sides hence: 7f + g - g = 5 - g so 7f = 5 - g now divide both sides by 7 (cancel(7) f)/cancel(7) = ( 5 - g …

2017年1月23日 · 730. By Defn., h(g(f(5)))=h[g{f(5)}] So, we first need f(5)=2(5)-1=9 rArr g(f(5))=g(9)=(3)(9)=27 rArr h[g{f(5)}]=h(27)=27^2+1=729+1=730.

2017年5月4日 · What does #f(x)=y# mean? How do you write the total cost of oranges in function notation, if each orange cost $3? How do you rewrite #s=2t+6# in function notation?

2017年4月3日 · (f+g)(x) = 3x^2 +x +2 (f+g)(x) = f(x) + g(x): (f+g)(x) = 3x^2 - x +5 + 2x - 3 Add like terms: (f+g)(x) = 3x^2 +(-x + 2x) + (5 - 3) (f+g)(x) = 3x^2 +x +2

2018年3月4日 · (f@g@h)(x) = 4x^2-8x+5 Given: { (f(x) = x^2+1), (g(x) = 2x), (h(x) = x-1) :} One way of thinking about these function compositions is to go back and forth between the symbols …

2016年1月25日 · f(g(x)) = 4x^2 + 9 > f(x) = 2x - 5 g(x) = 2x^2 + 7 To find f(g(x)), what you need to do is plug g(x) for ...

2018年1月9日 · #color(blue)("Preamble")# Note that #f and g# are just names. The question poser has assigned those names to the equation structures given.
