Question 1 of 10

Michigan Standards 7A-7IMedium Diagram

The graph shown most likely belongs to which polynomial?

AOdd-degree polynomial with positive leading coefficient

BEven-degree polynomial

COdd degree, negative leading coefficient

DA line

Explanation

Left end goes up (+∞), right end goes down (−∞). That signature is odd degree, negative leading coefficient.

Question 2 of 10

Michigan Standards 8A-8CEasy Diagram

Identify the conic.

AParabola

BCircle

CHyperbola

DEllipse

Explanation

Equal radii in all directions → a circle.

Question 3 of 10

Michigan Standards 5A-5CEasy Diagram

Which graph shows exponential decay?

AB (curve falling toward x-axis)

BA (curve rising)

CBoth

DNeither

Explanation

Exponential decay: starts high, falls toward zero. Graph B matches; graph A is exponential growth.

Question 4 of 10

Michigan Standards 5A-5CMedium Diagram

Which equation matches this exponential graph?

Ay = 2ˣ (growth)

By = x²

Cy = (1/2)ˣ (decay)

Dy = log₂(x)

Explanation

Curve approaches 0 as x → −∞ and grows rapidly as x increases → exponential growth.

Question 5 of 10

Michigan Standards 8A-8CEasy Diagram

Which conic equation does this represent?

ACircle: x² + y² = r²

BHyperbola

CParabola

DEllipse: x²/a² + y²/b² = 1

Explanation

Oval shape stretched horizontally → ellipse with horizontal major axis.

Question 6 of 10

Michigan Standards 5A-5CEasy Diagram

Which graph shows exponential growth?

AA — curve rising more steeply

BB — curve falling toward x-axis

CNeither

DBoth

Explanation

Growth: starts low, rises rapidly. A matches; B is decay.

Question 7 of 10

Michigan Standards 6M-6PEasy Diagram

Which graph corresponds to f(x) = 1/x?

AA line through the origin

BA two-branch hyperbola in quadrants I and III

CA V-shape

DA parabola opening up

Explanation

f(x) = 1/x has two branches: positive x → positive y (Q I), negative x → negative y (Q III), with asymptotes at the axes.

Question 8 of 10

Michigan Standards 6M-6PEasy Diagram

For the function whose graph approaches the dashed lines, what type of function is this most likely?

ARational function

BLinear function

CPolynomial

DAbsolute value

Explanation

Both vertical and horizontal asymptotes are characteristic of rational functions where degrees of numerator and denominator are similar.

Question 9 of 10

Michigan Standards 7A-7IEasy Diagram

How many real zeros does the polynomial graph show?

A3 real zeros

B4 real zeros

C2 real zeros

D1 real zero

Explanation

Real zeros = where the curve crosses the x-axis. Three crossings shown.

Question 10 of 10

Michigan Standards 7A-7IEasy Diagram

Match the end behavior to a possible polynomial.

Af(x) = x³ − 1

Bf(x) = x

Cf(x) = x⁴ − 2x²

Df(x) = −x⁴ + 1

Explanation

Both ends → +∞ matches even degree with positive leading. f(x) = x⁴ − 2x² qualifies.
