Question

Para cada função, determine:

F(x) = 2x² - x + 15
F(x) = 4x8

A) F (10)
B) F(5)
C)F(3)

Answer 1

Resposta:

Explicação passo-a-passo:

f(x) = 2x² - x + 15

f(10) = 2(10)² - 10 + 15

f(10) = 2*100 + 5

f(10) = 200 + 5

f(10) = 205

f(5) = 2(5)² - 5 + 15

f(5) = 2*25 + 10

f(5) = 50 + 10

f(5) = 60

f(3) = 2(3)² - 3 + 15

f(3) = 2*9 + 12

f(3) = 18 + 12

f(3) = 30

=======================================================

f(x) = 4x⁸

f(10) = 4(10)⁸

f(10) = 4*100000000

f(10) = 400000000

f(5) = 4(5)⁸

f(5) = 4*390625

f(5) = 1562500

f(3) = 4(3)⁸

f(3) = 4*6561

f(3) = 26244
