Exponents Rationals

When changing rational (fractional) exponents to radical form, the denominator of the fraction is the root or power?

• Root

• Power

When rewriting a radical in exponential form (fraction exponent), the power goes on the numerator or denominator of your fraction?

• Numerator

• Denominator

Simplify:

• 2

• 4

• 16

• 64

When is there no horizontal asymptote?

• the exponents in the numerator and denominator are equal

• the exponents in the denominator are greater than the numerator

• the exponents in the numerator are greater than the denominator

• the numerator equals zero

What is/are the x-intercepts/zeros of this graph?

• (-2,0) and (2,0)

• (-2,0)

• (3,0)

• (2,0) and (3,0)

This rational function has a horizontal asymptote at:

• y = 0

• y = 1

• y =7

• It has no HA

Find the hole of this function (if there is one).

• None

• (-4, 7/16)

• (4, 0)

• (1/2, 7/18)

What is the y-intercept?

• (0,1)

• (0,1/9)

• (0,-1/9)

• (0,-1)

Match the graph to the correct rational equation below.

• f(x)=x²/(x²+x-12)

• f(x)=4x²/(x²-x-12)

• f(x)=(2x²-2)/2x²

• f(x)=x/(x²+x-12)
