Write the function using function notation Let x be the inde

Write the function using function notation. Let x be the independent variable and y be the dependent variable. Use the letter f to name the function. y = x^2 + 5x - 7 A. y = f(x)-7 B. y = f(x)^2 + 5f(x) - 7 C. f(x) = x^2 + 5x D. f(x) = x^2 + 5x - 7

Answer is last option f(x)=x^2+5x-7 here x is the independent variable and the function f is dependent variable which depends up on x
