Answer:
There is a horizontal shift.
Step-by-step explanation:
Replacing x in a function formula with x - 8 moves the graph 8 units to the <u>right</u>.
In the attached image, y = sin(x) is light green, y = sin(x - 8) is dark green, and the arrows show how points on sin(x) get moved 8 units to the right.
To find where graph is intercepting x and y axis all we have to do is to calculate what is value of x when y = 0 (x intercept) and what value of y is when x = 0 (y intercept)
1) x = 0
-3y = 9
y = -3
2) y = 0
x = 9/2
Graph is bellow.
Answer:
0
Step-by-step explanation:
48 - 4(12)
48 - 48 = 0
Answer:
9 and -4
Step-by-step explanation:
change the word form to math form so now
x² - 36 = 5x <u>This look like a factoring problem, so we put it equal to 0</u>
x² - 5x - 36 = 0 <u>Now factor</u>
(x - 9) (x + 4) <u>We have to find 2 numbers that give -36 when we multiply and -5x when we add</u>
x - 9 = 0
x = 9
x + 4 = 0
x = -4
you can check by plugin the x value to actual equation.
