Jawaban:

1.

a. 43°C

b. 75°C

c. 79°C

d. 75°C

2.

a. -28

b. -5

c. 29

Penjelasan dengan langkah-langkah:

1.

masukkan saja, sesuai waktu.

a.

f(0)= 2(0)-18(0)+48(0)+43

f(0)= 43°C

b.

f(1)= 2(1)-18(1)+48(1)+43

f(1)= 2-18+48+43

f(1)= 2+30+43

f(1)= 75°C

c.

f(3)= 2(3)³-18(3)²+48(3)+43

= 2(27)-18(9)+144+43

= 54-162+144+43

= 54-18+43

= 36+43

= 79°C

d.

f(4)= 2(4)³-18(4)²+48(4)+43

= 2(64)-18(16)+192+43

= 128-288+192+43

= 75°C

2.

a.

f(-3)

= 11(-3)+5

= -33+5

= -28

b.

f(a)= -50

11a+5= -50

11a= -55

a= -5

c.

f(-1)= 11(-1)+5

= -11+5

= -6

f²(-1)+2f(-1)+5

= (-6)²+2(-6)+5

= 36-12+5

= 24+5

= 29
