What are co-terminal angles?

Back

Co-terminal angles are angles that share the same terminal side when drawn in standard position. They can be found by adding or subtracting multiples of 360° (or 2π radians) to/from the angle.

Front

How do you find co-terminal angles for -75°?

Back

To find co-terminal angles for -75°, add 360°: -75° + 360° = 285°. You can also subtract 360°: -75° - 360° = -435°. Thus, -75°, 285°, and -435° are co-terminal.

What is the value of f(-5) for the function f(x) = 2x² - 3x?

Back

f(-5) = 2(-5)² - 3(-5) = 2(25) + 15 = 50 + 15 = 65.

Front

What is the value of g(1) for the function g(x) = 6x + 2?

Back

g(1) = 6(1) + 2 = 6 + 2 = 8.

Front

What is f(-5) + g(1) for the functions f(x) = 2x² - 3x and g(x) = 6x + 2?

Back

f(-5) + g(1) = 65 + 8 = 73.

Front

What is the expression for f(x+h) if f(x) = x²?

Back

f(x+h) = (x+h)² = x² + 2xh + h².

Front

What is the value of f(x+h) - f(x) for f(x) = x²?

Back

f(x+h) - f(x) = (x² + 2xh + h²) - x² = 2xh + h².
