Question

f(x) = 4x + 5
f(x) = x4 – 7x
f(x) = 2x12 + 10x – 3
f(x) = 7x5 – 7x3 + 6x – 8​

Answer 1

Respuesta:

1.f(x) = 4x + 5

• f(x)= - $\frac{5}{4}$

• x= -1 $\frac{1}{4}$,x = - 1,25

2. f(x) = x4 – 7x (hallar intersección / cero en x)

• $x_{1}$ =0,$x_{2}$ =$\sqrt[3]{7}$

• $x_{1}$ =0, $x_{2}$ ≈ 1,91293

3. f(x) = 2x12 + 10x – 3

• f(0)=2×$0^{12}$ + 10×0-3
• f(0)=2×0+0-3
• f(0)=-3

4.f(x) = 7x5 – 7x3 + 6x – 8​

• f(0)=7×$0^{5}$-7×$0^{3}$+6×0-8
• f(0)=7×0-7×0+0-8
• f(0)=-8
