Question

Si f(x) = 5x 2 + 3x – 6 Hallar a) f(0) b) f(-5) c) f (5)​

Answer 1

Respuesta:

f(x) = 5x²+3x-6

f(0) = 5(0)²+3(0)-6

f(0) = 5(0)+0-6

f(0) = 0-6

f(0) = -6

f(5) = 5(5)²+3(5)-6

f(5) = 5×25+15-6

f(5) = 125+15-6

f(5) = 140-6

f(5) = 134

f(-5) = 5(-5)²-3(-5)-6

f(-5) = 5(25)-(-15)-6

f(-5) = 125+15-6

f(-5) = 125+(15-6)

f(-5) = 125+9

f(-5) = 134

R// f(0) vale -6 , f(5) vale 134 y f(-5) vale 134
