Equation Function

Does this graph in the back have maximum or minimum value?

• maximum

• minimum

• neither

• both

The minimum point of this graph is...

• (0,4)

• (0,-4)

• (-2,0)

• (2,0)

Solve for x; x + 2w = m

• x = m - 2w

• x = 0.5m - w

• x = 2mw

• x = m/(2w)

Solve for x.

• x = yb - v

• x = by - v

• x = by + v

• h=V/(3πr²)
• h=(3V)/(πr²)
• h=V/(3πr²)
• h=(3π)/(Vr²)

• Function
• Not a Function

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.

• Yes, because each x-value has only one y-value paired with it.

• No, because the x-value 11 has two y-values pair with it.

• No, because each x-value has only one y-value paired with it.

Solve for m

E = mc²

• m = square root (E/c)

• m = square root(E) /c

• m = E /c²

• m = c²/E

Is this table a function or not a function? 

• Function

• Not a Function

Does the following quadratic equation have a maximum or minimum value? How can you tell?
y=x²+2x-3

• Minimum value, because the a value is positive

• Maximum value, because the b value is positive

• Maximum value, because the a value is positive

• Minimum value, because the c value is negative
