Question

If g(x) = x^2 - x, find g for the given values of x.

A) g(-3) = 18
B) g(7) = 42
C) g(8) = 56
D) g(-10) = 110
E) True

Answer 1

For the function g(x) = x^2 - x, the values of g(-3), g(7), g(8), and g(-10) were calculated, with correct answers being 12, 42, 56, and 110, respectively; only option A was incorrect.

Step-by-step explanation:

When given the function g(x) = x^2 - x, we can find the value of g for any given x by substituting the value of x into the function. Let's calculate g for the specified values:

• g(-3) = (-3)^2 - (-3) = 9 + 3 = 12, not 18.
• g(7) = (7)^2 - (7) = 49 - 7 = 42, which matches the given value.
• g(8) = (8)^2 - (8) = 64 - 8 = 56, which matches the given value.
• g(-10) = (-10)^2 - (-10) = 100 + 10 = 110, which matches the given value.

From these calculations, we find that options B, C, and D are correct, while option A is incorrect.
