Answer:
None of the above
Step-by-step explanation:
A graph of the function f(x) = 4x- 8 is straight line passing through (0,-8) on y axis and (2,0) on x axis.
Thus, we observe that both Domain and Range belongs R (real no.), but none of above options states that.
3. The second line should be
or 
3. So the roots are
or 
Step-by-step explanation:
Step 1:
If the function equals 0, we substitute all the separate factors to 0.
We keep the variable on the left side while all the other values go to the right side.
The given equation is 
Step 2:
As given in step 1, we substitute all the separate factors to 0.
So
or 
So the roots are


So the roots are
or 
Answer:
3.65102725271
Step-by-step explanation:
Answer:
Step 1:
Find the vertex. Since the equation is in vertex form, the vertex will be at the point (h, k).
Step 2:
Find the y-intercept. To find the y-intercept let x = 0 and solve for y.
Step 3:
Find the x-intercept(s). To find the x-intercept let y = 0 and solve for x. You can solve for x by using the square root principle or the quadratic formula (if you simplify the problem into the correct form).
Step 4:
Graph the parabola using the points found in steps 1 – 3.
