Question

Dada la función f(x) = 2x² + 4x − 5,

calcule f(5)/f(−2)
A) −115/23
B) −35/23
C) −13
D) −35/13

Answer 1

Explicación paso a paso:

F(5)= 2•5²+4•5-5

=50+20-5

=65

F(2)=2•2²+4•2-5

=8+6-5

=9

F(5)/F(2)

=65/9

=7.222

Answer 2

Respuesta:

2×25+4×5-5

50+20-5

=65

2×4+4×2-5

8+8-5

11

65/11=5.9
