Tiesinę priklausomybę galima išreikšti formule

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

f(x) = 2 + 4xf\left(x\right)\ =\ -2\ +\ 4x

f(t) = 3x3 +1f\left(t\right)\ =\ -3x^3\ +1

f(x) = 0,3x + 42xf\left(x\right)\ =\ -0,3x\ +\ 4^2x

Dviejų dydžių tiesioginis proporcingumas yra užrašomas

f(x) =2 3x2f\left(x\right)\ =2-\ 3x^2

f(x) =5x+1f\left(x\right)\ =5x+1

f(x) =2x f\left(x\right)\ =\frac{2}{x}\

f(x) =4xf\left(x\right)\ =-4x

Nurodykite pavaizduotos funkcijos išraišką ir koeficiento a ženklą.

f( x )=ax+1f\left(\ x\ \right)=ax+1 a > 0

f(x) =axf\left(x\right)\ =\frac{a}{x} a <0

f(x) = xaf\left(x\right)\ =\ \frac{x}{a} a > 0

f (x ) = a2f\ \left(x\ \right)\ =\ \frac{a}{2} a < 0
