Answer:

A. 41

Step-by-step explanation:

5a - b² + 2c(a-b)

Put a = 2, b = -3, and c = 4.

5(2) - (-3)² + 2(4)(2-(-3))

Evaluate.

10 - 9 + 2(4)(2+3)

10 - 9 + 8(5)

10 - 9 + 40

1 + 40

= 41

Answer:

41

Step-by-step explanation:

Given that,

a = 2 \\ b =  - 3 \\ c = 4

Let's solve now,

5a -  {b}^{2}  + 2c(a - b) \\ 5 \times 2 - ( { - 3}^{2} ) + 2 \times 4(2 - ( - 3)) \\ 10 - ( - 3 \times  - 3) + 8(2 + 3) \\ 10 - 9 + 8 \times 5 \\ 10 - 9 + 40 \\  1 + 40 \\  = 41

List the sequence of transformations. ()=−2(−3)^4+1
SVEN [57.7K]

We have the function:

()=−2(−3)^4+1

We need to go from this equation to the parent function x^4. To do that, we first do a vertical translation of 1 unit below. That is:

Vertical translation: f(x) - 1

= −2(−3)^4

Now, we make a horizontal shift of 3 units to the left, replacing x by x + 3:

f(x + 3) + 1 = −2()^4

Horizontal shift: f(x + 3) - 1

= −2x^4

We can make a horizontal expansion if we multiply this function by 1/2:

Horizontal expansion: ( f(x + 3) - 1 ) / 2

= -x^4

Finally, we make a reflection around the x-axis by multiplying this result by -1:

x-axis reflection: -( f(x + 3) - 1 ) / 2

= x^4
