The output values of f(8x²), f(8x²+9x) and f(-8x²) in the given function are -24x² + 4, -24x² - 27x + 4 and 24x² + 4 respectively.
What are the output values of f(8x²), f(8x²+9x) and f(-8x²) in the given function?
Given the function in the question;
- f(8x²) = ?
- f(8x²+9x) = ?
- f(-8x²) = ?
To determine the output of f(8x²), replace all the occurrence of x in the function with 8x² and simplify.
f(x) = -3x + 4
f(8x²) = -3(8x²) + 4
f(8x²) = -24x² + 4
To determine the output of f(8x²+9x), replace all the occurrence of x in the function with 8x²+9x and simplify.
f(x) = -3x + 4
f(8x²+9x) = -3(8x²+9x) + 4
f(8x²+9x) = -3(8x²+9x) + 4
f(8x²+9x) = -24x² - 27x + 4
To determine the output of f(-8x²), replace all the occurrence of x in the function with -8x² and simplify.
f(x) = -3x + 4
f(-8x²) = -3(-8x²) + 4
f(-8x²) = 24x² + 4
Therefore, the output values of f(8x²), f(8x²+9x) and f(-8x²) in the given function are -24x² + 4, -24x² - 27x + 4 and 24x² + 4 respectively.
