MULTIPLE CHOICE QUESTION

5 mins • 1 pt

 f(x)=x2+xf\left(x\right)=x^2+x  och  g(x)=exg\left(x\right)=e^x  

 h(x)=f(x)+g(x)h\left(x\right)=f\left(x\right)+g\left(x\right)  

 h(x)=e2x+exh\left(x\right)=e^{2x}+e^x  

 h(x)=ex2+xh\left(x\right)=e^{x^2+x}  

 h(x)=(x2+x)⋅exh\left(x\right)=\left(x^2+x\right)\cdot e^x  

 h(x)=x2+x+exh\left(x\right)=x^2+x+e^x

 h(x)=f(x)⋅g(x)h\left(x\right)=f\left(x\right)\cdot g\left(x\right)  

 h(x)=e2x+exh\left(x\right)=e^{2x}+e^x  

 h(x)=ex2+xh\left(x\right)=e^{x^2+x}  

 h(x)=(x2+x)⋅exh\left(x\right)=\left(x^2+x\right)\cdot e^x  

 h(x)=x2+x+exh\left(x\right)=x^2+x+e^x

MULTIPLE CHOICE QUESTION

5 mins • 1 pt

 f(x)=x2f\left(x\right)=x^2   och  g(x)=x+3g\left(x\right)=x+3  

 h(x)=(x+3)2h\left(x\right)=\left(x+3\right)^2  

 h(x)=f(g(x))h\left(x\right)=f\left(g\left(x\right)\right)  

 h(x)=g(f(x))h\left(x\right)=g\left(f\left(x\right)\right)  

 h(x)=f(x)⋅g(x)h\left(x\right)=f\left(x\right)\cdot g\left(x\right)  

Answer explanation

Först lägger jag till 3, sedan kvadrerar, därför sitter g(x) inuti f(x),
därmed är svaret  f(g(x))f\left(g\left(x\right)\right)

MULTIPLE CHOICE QUESTION

5 mins • 1 pt

 f(x)=x2f\left(x\right)=x^2   och  g(x)=x+3g\left(x\right)=x+3  

 h(x)=x2(x+3)h\left(x\right)=x^2\left(x+3\right)  

 h(x)=f(g(x))h\left(x\right)=f\left(g\left(x\right)\right)  

 h(x)=g(f(x))h\left(x\right)=g\left(f\left(x\right)\right)  

 h(x)=f(x)⋅g(x)h\left(x\right)=f\left(x\right)\cdot g\left(x\right)  

Answer explanation

De sitter bredvid varandra:
man kvadrerar x-et, lägger till 3 till ett annat x och sedan multiplicerar ihop
finns ingen given ordning i vilken man ska göra saker

MULTIPLE CHOICE QUESTION

5 mins • 1 pt

 f(x)=xf\left(x\right)=\sqrt{x}   och  g(x)=x+3g\left(x\right)=x+3  

 h(x)=x(x+3)h\left(x\right)=\sqrt{x}\left(x+3\right)  

 h(x)=f(g(x))h\left(x\right)=f\left(g\left(x\right)\right)  

 h(x)=g(f(x))h\left(x\right)=g\left(f\left(x\right)\right)  

 h(x)=f(x)⋅g(x)h\left(x\right)=f\left(x\right)\cdot g\left(x\right)  

 h(x)h\left(x\right)  är inget av det

Answer explanation

De sitter bredvid varandra: man drar roten ur  x-et, lägger till 3 till ett annat x och sedan multiplicerar ihop

finns ingen given ordning i vilken man ska göra saker
