Answer:When solving a question like "What number is 4 less than 9?", take a close look at what it is really asking.

You have the number 9 and you are looking for a number that is 4 less than 9. In other words, if you have 9 and take away 4, then how many do you have?

You guessed it! This is a subtraction problem. 9 is the minuend and 4 is subtrahend and the answer we are looking for is the difference.

Therefore, to solve "What number is 4 less than 9?", you subtract 4 from 9 like so:

9 - 4 = 5

The graph of f ′ (x), the derivative of f of x, is continuous for all x and consists of five line segments as shown below. Given
myrzilka [38]

Answer

10.5

Step-by-step explanation:

The other answer is correct until solving for C.  f(-3) = 6, not -6.  So C = 21/2.  This makes f(0) = 10.5.  Local Max should occur at x intercepts on the f'(x) graph.

Make a table of values for f(x) = 18x2 + 10x + 1.
serg [7]

Answer/step-by-step explanation:

To make a table of values, substitute each value of x into the given equation function f(x) = 18x^2 + 10x + 1

For x = -3,

f(-3) = 18(-3)^2 + 10(-3) + 1

f(-3) = 18(9) + (-30) + 1

f(-3) = 162 - 30 + 1 = 133

For x = -2,

f(-2) = 18(-2)^2 + 10(-2) + 1

f(-2) = 18(4) + (-20) + 1

f(-2) = 72 - 20 + 1 = 53

For x = -1,

f(-1) = 18(-1)^2 + 10(-1) + 1

f(-1) = 18(1) + (-10) + 1

f(-1) = 18 - 10 + 1 = 9

For x = 0,

f(0) = 18(0)^2 + 10(0) + 1

f(0) = 18(0) + 0 + 1

f(0) = 0 - 0 + 1 = 1

For x = 1,

f(1) = 18(1)^2 + 10(1) + 1

f(1) = 18(1) + 10 + 1

f(1) = 18 + 10 + 1 = 29

For x = 2,

f(2) = 18(2)^2 + 10(2) + 1

f(2) = 18(4) + 20 + 1

f(2) = 72 + 20 + 1 = 93

For x = 3,

f(3) = 18(3)^2 + 10(3) + 1

f(3) = 18(9) + 30 + 1

f(3) = 162 + 30 + 1 = 193
