Question

Given f(x) = 2x² - x - 12, find f (8)

Answer 1

`\huge\text{Hey there!}`

`\mathsf{f(x) = 2x^2 - x - 12}`

`\mathsf{f(x) = 2(8)^2 - 8 - 12}`

`\mathsf{f(x) = 2(8^2) - 8 - 12}`

`\mathsf{f(x) = 2(8 * 8) - 8 - 12}`

`\mathsf{f(x) = 2(64) - 8 - 12}`

`\mathsf{f(x) = 128 - 8 - 12}`

`\mathsf{f(x) = 120 - 12}`

`\mathsf{f(x) = 108}`

`\huge\text{Therefore your answer should be: }`

`\huge\boxed{\mathsf{f(x) = 108}}\huge\checkmark`
