It is a constant function, y = -12

If you have to choose from linear and exponential, then you can go with linear function.

Hope it helps!

The roots of x2 − ( ) + 34 are 5 ± 3i.

Angelina_Jolie [31]

Use quadratic formula
if you had ax^2+bx+c=0, then
x= $\frac{-b+/- \sqrt{b^{2}-4ac} }{2a}$
a=1
b=?
c=34
subsitute
$\frac{-b+/- \sqrt{b^{2}-4(1)(34)} }{2(1)}$ =5+/-3i
$\frac{-b+/- \sqrt{b^{2}-136} }{2}$ =5+/-3i
make 5+/-3 into fraction over 2,(10+/-6i)/2
$\frac{-b+/- \sqrt{b^{2}-136} }{2}$ =(10+/-6i)/2
multiply both sides by 2
$-b+/- \sqrt{b^{2}-136}$ =10+/-6i
we conclude that -b=10
b=-10

ok so equaton is
x^2-10x+34

Is the relation shown in the arrow diagram a function?

rewona [7]

Answer: A) Yes. Every unique input has a unique output.

In other words, each x value maps to exactly one y value, so that's why we have a function.
