The graph of a function can be sketched by plotting points.
First and foremost, it is to be determined if the function is odd/even or periodic. Next, we find the x and y intercepts. To sketch a graph of a function, one can start by plotting a few points that lie on the graph using the coordinates given by the function. For example, if the function is y = x², then points (0, 0), (1, 1), and (2, 4) can be plotted by substituting the values of x into the function to find the corresponding values of y.
Subsequent to this, one can connect the points with a smooth curve to form the graph of function. If the function is a straight line, the graph will be a straight line. If the function is quadratic, the graph will be a parabola. The graph may take on a more complicated shape for more complex functions.

we have that
y = 3x + 5
and that
z = x² + 2x - 5
we want to know what yz or y·z is equal to
we have what y and z are equal to so we can multiply them together
(3x+5)(x²+2x-5)
first we multiply each value in the second set of parentheses by 3x and then multiply each value in the second set of parentheses by 5 and then combine like terms.
(3x+5)(x²+2x-5)
3x³+6x²-15x + 5x² +10x -25
3x³ + 11x² -5x -25
so your answer should be
D) 3x³+11x²-5x-25
Answer:
3rd answer
Step-by-step explanation:
because for the width of the first rectangle (27 cm) it is just 3 times larger for the width of the second rectangle (9 cm)
same for the length, 33cm is 3 timer larger
also sorry if its the other way around, i just call the ones that are like "______" length
Answer:
x = 6
Step-by-step explanation:
x+4−4=10−4
x=6
Answer: x=3
