Given the piecewise function. Shown below
creativ13 [48]

Answer:

  (x, g(x)) = {(-2, -2), (0, 0), (2, 2), (4, -3), (6, -3)}

Step-by-step explanation:

The first three values of x in the table are all less than or equal to 2, so the first part of the function definition applies. The y-value is equal to the x-value. The ordered pairs are ...

  (-2, -2), (0, 0), (2, 2)

The last two values of x in the table are more than 2, so the last part of the function definition applies. For those values of x, the y-value is -3. The ordered pairs are ...

Evaluate the polynomial when a.x=0 and b.x=-1<br> x2 – 3x - 7
Arlecino [84]

Answer:

a) -7 & b) -6

Step-by-step explanation:

Here,

a) x = 0

Solution ↦

x2 - 3x - 7 \\  =  0 \times 2 - 3 \times 0 - 7 \\  =  - 7

b) x = -1

Solution ↦

x2 - 3x - 7 \\  =  - 1 \times 2 - 3 \times ( - 1) - 7 \\  =  - 2 + 3 - 7 \\  =  - 9 + 3 \\  =  - 6
