It's the graphs that don't touch the x-axis have complex roots. Roots are the points where the parabola touches the x-axis. A,C and E all cross/touch the x-axis so they have real roots.


non-real or complex root parabolas are: B, D, F

Answer:

The functions that have complex roots are functions B; D; and F

Step-by-step explanation: Based on the graph, look for any parabolas, or functions, that appear to not touch the x or y axis.

If f(x)= 3x^2+1 and g(x)= 1-x, what is the value of (f-g)(2)?
enyata [817]

Answer:

14

Step-by-step explanation:

note that (f - g) = f(x) - g(x)

f(x) - g(x) = 3x² + 1 - (1 - x) = 3x² + 1 - 1 + x = 3x² + x

To evaluate (f - g)(2) substitute x = 2 into f(x) - g(x)

(f - g)(2) = 3(2)² + 2 = (3 × 4) + 2 = 12 + 2 = 14

Mumz [18]

Answer:

m = 9  

It means that you are multiplying each of the values inside the parentheses by 2.

Step-by-step explanation:

2(m + 2) = 22

2m + 4 = 22

2m + 4 - 4 = 22 - 4

2m = 18                           -Divide both sides by 2

m = 9
