Answer 1

Answer:

Hi there!

Your answers are:

1. 21

1. 12

Step-by-step explanation:

1. The derivative of 2x^2 +x -1 is equal to 4x+1

Now, plug in x= 5 into 4x+ 1

4(5) +1

20+1

21

2. The derivative of 12x -6 is equal to 12

that means:

f(x) = 12

f(x) = 12AND

f(x) = 12ANDf(3) = 12

Hope this makes sense! (updated)
