Answer:
yes because When you are given an equation and a specific value for x, there should only be one corresponding y-value for that x-value. For example, y = x + 1 is a function because y will always be one greater than x. Equations with exponents can also be functions.
Step-by-step explanation:
The notation y = f(x) defines a function named f. This is read as “ y is a function of x.” The letter x represents the input value, or independent variable. The letter y, or f(x), represents the output value, or dependent variable.
Answer:
b. 6
Step-by-step explanation:
Please use " ^ " to denote exponentiation: <span>y=x^2+5x−7.
Borrow "x+5" from the first equation and replace y in the second with that:
x+5 = x^2 + 5x - 7. Then x^2 + 5x - 7 - x - 5 = 0, or x^2 + 4x -12 = 0.
This is easily factored: (x-2)(x+6)=0, so that x=2 and x=-6.
Using y = x+5, find y for x=2 and then y for x=6.</span>
