Question

dada função f (×)=8×+15 calcule f (0)-f (3)=

Answer 1

$ola \\ \\ f(0) = 8x + 15 \\ f(0) = 8 \times 0 + 15 \\ f(x) = 0 + 15 \\ f(x) = 15 \\ \\ f(3) = 8x + 15 \\ f( 3) = 8 \times 3 + 15 \\ f(3) = 24 + 15 \\ f(3) = 39 \\ \\ f(0) - f(3) 15 - 39 = - 24 espero \: ter \: ajdado. \: bons \: estudos.$

Answer 2

f (×)=8×+15
calcule f (0) - f (3)

f(0) = 8.0+15 = 15
f(3) = 8.3+15 = 24+15 = 39

= f(0) - f(3)
= 15 - 39
= - 24
