Answer:
Hi there!
Your answers are:
Step-by-step explanation:
1. The derivative of 2x^2 +x -1 is equal to <u>4</u><u>x</u><u>+</u><u>1</u>
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
<u>Hope</u><u> </u><u>this </u><u>makes</u><u> </u><u>sense</u><u>!</u><u> </u><u>(</u><u>updated</u><u>)</u>
x=1/252
x=0.00396825
Hope this helped!!!
