Please help! I will give the brainliest if you give me a good answer. Calculate the derivative of the following functions at the indicated point:

Hi there!

Your answers are:

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)

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis
