In mathematics, a constant function is one defined in
which a function whose output value (y) is the same for every value of the
input variable (x). Therefore this means that whatever is the value for x, the
value of y would always be the same. Hence we can say that the function is a
straight horizontal line in a Cartesian plane.
Since the value of y does not change, and the average rate
of change has the formula:
average rate of change = (y2 – y1) / (x2 – x1)
So y2 – y1 = 0 therefore average rate of change is also
zero.
Hence to complete the sentence:
For a constant function, the y-coordinate is <u>the same</u> for
every pair of points selected, so the average rate of change always has a value
equal to <u>zero</u>.
Answer:
D. x = 1.7 or x = 5.7
Step-by-step explanation:
The left side of the equation is graphed in blue. The right side of the equation is graphed in red.
The solution of the equation is the x (and y) that make both equations true.
On the graph these solutions are the points where the two graphs intersect.
Those two points have x values that are positive (and y's that are negative) Only answer D. has x-values that correspond to the x-values of the points of intersection.
The answer is 3..y=mx+b where m is the slope
45 + 4 makes 49 if that counts
