Answer:
Step-by-step explanation:
g(x) = 3f(-2x)
= 3*([-2x)² + (-2x) - 2)
= 3 (4x² - 2x - 2)
= 3 * (4x² - 4x +2x - 2) {Rewrite the middle term}
= 3 *[ 4x(x - 1) + 2(x - 1)]
= 3* [ (x -1) *(4x + 2)]
= 3(x - 1)(4x + 2)
x - 1 = 0 ; 4x + 2 = 0
x = 1 ; 4x = -2
x =
Roots: x = 1 , (-1/2)
y=2
Explanation
Step 1
The y -intercept of a graph is the point where the graph crosses the y -axis.
so , let's check the graph
therefore, the y-intercept is 2
Step 2
The positive regions of a function are those intervals where the function is above the x-axis. It is where the y-values are positive (not zero)
hence, the function is potive in ( in x axis)
Step 3
negative region
The negative regions of a function are those intervals where the function is below the x-axis. It is where the y-values are negative (not zero).
