GIVE THE RESULT AND THE INTERVAL NOTATION.

False, True, False - Interval Notation: [-5, 4]

GIVE THE INTERVAL NOTATION OF:

(-∞,−4) ∪ [6,∞)

If c varies directly as the square of d, and c=1 when d=4, find the constant of variation.

k = 1/16

y varies directly as x. if y = 12 when x = 4, what is x when y is 36?

x is 12 wheny y = 36

If a varies directly as the square of b, and a=6 when b=9, find the constant of variation.

k = 2/27

If y varies directly as x and y=15 when x=24, find the constant of variation.

k = 5/8

Write the given mathematical expression into words. b= kc

b varies directly as c

Write the given statement into mathematical expression. The weight of an object on earth (E) varies directly as the weight of the same object on the moon (m)

E = km

Write the given statement into mathematical expression. The work done (d) varies directly as the number of men (m) at work.

d=km

Write the given statement into mathematical expression. a varies directly as b

a=kb

Change the given function to standard form.

y=2x^2 − 8x + 6

Change the given function to vertex form.

y=(x−1)^2−?

Change the given function to vertex form.

y=2(x−2)^2+1

It is a situation in which two quantities-such as hours, pay, or distance and time –increase at the same rate.

Direct Variation

The graph of a quadratic function is _____.

Parabola

GIVE THE STANDARD FORM OF QUADRATIC FUNCTION.

f(x)=ax^2+bx+c

The vertical line that passes through the vertex and divides the parabola equally.

Axis of Symmetry

It is a function whose degree is 2 and where y is not always exactly equal to the function
