Evaluate the expression 4a+2b^2 when a=3 and b=2

20

Step-by-step explanation:

1. Plug in the numbers.

4(3)+2(2)^2

2. Evaluate. (PEDMAS/BEDMAS)

Since there is an exponent in this equation, do it first.

(2(2)^2), 2 to the exponent of 2 is 4:

2(4)

Now lets continue and finish off:

4(3) + 2(4)

4x3 = 12, 2x4 = 8:

3. Answer

12 + 8 = 20

the answer is true.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
