Answer:
f(x) - 3 is translated 3 units down and -2*f(x) is reflected across x-axis.
Step-by-step explanation:
We have, f(x) becomes f(x) - 3.
The y-intercept of f(x) is f(0), this implies y-intercept of f(x) -3 is f(0) - 3. This means that the graph of f(x) is translated 3 units down.
Next, we have f(x) becomes -2*f(x).
The y-intercept of -2*f(x) is -2*f(0) and it means that first the graph of f(x) is stretched horizontally by 2 units and then reflected across x-axis.
As, the function f(x) is multiplied by 2, this implies that resultant function -2*f(x) will be an even function and its graph will be symmetric about y-axis.
Moreover, the function -2*f(x) increases wherever f(x) decreases and vice-versa.
In mathematics. 256 is a composite number, with the factorization 256 = 28, which makes it a power of two. 256 is 4 raised to the 4th power, so in tetration notation 256 is 24.
32+56*45
Remember PEMDAS, so we have to solve the multiplication part of the expression first....
32+2520
Now we solve for the addition
2552
Answer=2552
{ 8, -6 } as you multiply the first equation with 1.25 to get :
then, you use elemination by substraction to get rid of x:
try to solve for y to get y = -6, and then you use either equation 1 or 2 to find the value of x, which in both cases is equal to 8.
