G and Consider the following. f(x) = 4x2 + 5x − 18 (a) Find the instantaneous rate of change of the function at the value x = −4. f '(−4) = (b) Find the slope of the tangent at the value x = −4.

a) , b)

Step-by-step explanation:

a) The instantaneous rate of change is:

b) The slope of the tangent line is equal to the instantaneous rate of change found previously.

answer: just subtact the units and then add the non negative : happy to

step-by-step explanation:

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
