Answer from: villafana36

1) f(0)= -6 , f(2)= -12, f(-1)= 0, f(6)= 0

2) f(0)= -12 , f(2)= -8 , f(-1)= -14 , f(6)= 168

3) f(0)= 5 , f(2)= 20, f(-1)= 2.5 , f(6)= 320

Step-by-step explanation:

1) The given function is f(x) = x² – 5x – 6.

To find the values of f(0) , f(2), f(-1), f(6) :

Substitute x=0 in f(x) = x² – 5x – 6

f(0) = -6

Therefore, f(0) = -6

Substitute x=2 in f(x) = x² – 5x – 6

f(2) = (2)² -5(2)-6

⇒ 4-10-6

⇒ 4-16

⇒ -12

Therefore, f(2) = -12

Substitute x= -1 in f(x) = x² – 5x – 6

f(-1) = (-1)² - 5(-1) -6

⇒ 1+5-6

⇒ 6-6

⇒ 0

Therefore, f(-1) = 0

Substitute x= 6 in f(x) = x² – 5x – 6

f(6) = (6)² - 5(6) -6

⇒ 36 -30 -6

⇒ 36-36

⇒ 0

Therefore, f(6) = 0

2) The given function is f(x) = x³– x²–12.

To find the values of f(0) , f(2), f(-1), f(6) :

Substitute x=0 in f(x) = x³– x²–12

f(0) = -`12

Therefore, f(0) = -12

Substitute x= 2 in f(x) = x³– x²–12

f(2) = (2)³ - (2)² -12

⇒ 8-4-12

⇒ 8-16

⇒ -8

Therefore, f(2) = -8

Substitute x= -1 in f(x) = x³– x²–12

f(-1) = (-1)³ - (-1)² -12

⇒ -1-1-12

⇒ -14

Therefore, f(-1) = -14

Substitute x= 6 in f(x) = x³– x²–12

f(6) = (6)³ - (6)² -12

⇒ 216 -36 -12

⇒ 216-48

⇒ 168

Therefore, f(6) = 168

3) The given function is f(x) = $5.24^{x}$

To find the values of f(0) , f(2), f(-1), f(6) :

Substitute x=0 in f(x) = $5.2^{x}$

f(0) = 5 × $2^{0}$

Any number with power zero is 1.

f(0) = 5

Therefore, f(0) = 5

Substitute x=2 in f(x) = $5.2^{x}$

f(2) = 5 × 2²

⇒ 5×4

⇒ 20

Therefore, f(2) = 20

Substitute x= -1 in f(x) = 5.2{x}

f(-1) = $5\times2^{-1}$

⇒ 5 × 1/2

⇒ 5 × 0.5

⇒ 2.5

Therefore, f(-1) = 2.5

Substitute x= 6 in f(x) = $5.2^{x}$

f(6) = $5\times 2^{6}$

⇒ 5 × 64

⇒ 320

Therefore, f(6) = 320
