Respuesta:
1.f(x) = 4x + 5
- f(x)= - [tex]\frac{5}{4}[/tex]
- x= -1 [tex]\frac{1}{4}[/tex],x = - 1,25
2. f(x) = x4 – 7x (hallar intersección / cero en x)
- [tex]x_{1}[/tex] =0,[tex]x_{2}[/tex] =[tex]\sqrt[3]{7}[/tex]
- [tex]x_{1}[/tex] =0, [tex]x_{2}[/tex] ≈ 1,91293
3. f(x) = 2x12 + 10x – 3
- f(0)=2×[tex]0^{12}[/tex] + 10×0-3
- f(0)=2×0+0-3
- f(0)=-3
4.f(x) = 7x5 – 7x3 + 6x – 8
- f(0)=7×[tex]0^{5}[/tex]-7×[tex]0^{3}[/tex]+6×0-8
- f(0)=7×0-7×0+0-8
- f(0)=-8
