Algebra 1 Units 1 and 2

What is the result of -3 times -10 divided by 5, then add 1?

• 5

• 6

• 7

• 8

• By adding 15 to the function value

• By dividing 15 by 5 and squaring the result

• By taking the square root of 15 and multiplying by 5

Continuous, Discrete, or Neither

• Continuous (smooth curve)

• Discrete (disconnected points)

• Neither (random points)

• Both (mixed points)

A rental company charges $2 per hour to rent a bicycle. A table showing the prices of renting one bicycle for different amounts of time is shown. Which type of function?

• increasing linear

• decreasing linear

• increasing exponential

• decreasing exponential

Identify where the function is negative (what x values)

• -4 < x < 3

• -5 < x < 2

• -3 < x < 4

• -6 < x < 1

Linear or non-linear

• Linear (Ax + By = C)

• Non-linear (e.g., y = x^2)

• Quadratic (e.g., y = ax^2 + bx + c)

• Exponential (e.g., y = a * b^x)

Estimate the y-intercept

• (0, -10)

• (0, -12)

• (0, -8)

• (0, -15)

Identify the x-intercepts

• (-4, 0) and (3, 0)

• (0, -4) and (0, 3)

• (-3, 0) and (4, 0)

• (-4, 0) and (0, 3)

Identify where the function is positive (what x values)

• x < -4 and x > 3

• -4 < x < 3

• x = -4 or x = 3

• x > -4 and x < 3

Continuous, Discrete, or Neither?

• Continuous

• Discrete

• Neither (some connected, some not)

• Both Continuous and Discrete
