Evaluate the expression when a=3 and b=4

The answer to this problem is 22.

Step-by-step explanation:

To solve this problem, we simply need to plug in the values given for a and b into the expression given and simplify.

We are given that a=3 and b=4, thus, these are the numbers we will plug in before we simplify.

2a^2 + b =

2(3)^2 + 4

Next, we should follow the rules of PEMDAS.  This tells us that we should solve the parentheses first, but since there are no parentheses, we can move onto exponents.

If we simplify, we get:

2(9) + 4

Next, we should perform the multiplication.

18 + 4

Finally, we can add together the remaining terms.

18 + 4 = 22

Therefore, your answer is 22.

First you must substitute a and b for the corresponding values:

a = 3

b = 4

so...

2* + 4

Now you must evaluate using the rules of PEMDAS (Parentheses, Exponent, Multiply, Divide, Add, Subtract)

There are no parentheses so skip that step and go on to the next one, exponent, which is

= 3*3

9

^^^Replace with 9

2 * 9 + 4

The next step is multiply 2 and 9

2*9 = 18

^^^Replace 2*9 with 18

18 + 4

Now add 18 and 4 together

22

step-by-step explanation:

we have the parent function given by,

1. the function is translated 5 units to the left.

so, we get,   becomes

2. the function is translated 5 units to the right.

so, we get,   becomes

3. the function is translated 5 units upwards.

so, we get,   becomes

4. the function is translated 5 units downwards.

so, we get,   becomes

5. the function is reflected across x-axis.

so, we get,   becomes

6. the function is reflected across y-axis.

so, we get,   becomes .
