Answer 2

А) f(x) = 7 - 5x: This is a linear function, which means it represents a straight line on a graph. The function takes an input value x and returns an output value according to the formula f(x) = 7 - 5x. In this formula:

• The constant term 7 represents the y-intercept, which is the value of the function when x = 0. So, the point (0, 7) is on the graph.
• The coefficient of x, which is -5, represents the slope of the line. It tells you that for every unit increase in x, the value of the function decreases by 5 units. So, the slope of the line is negative.

If you were to graph this function, you would get a straight line that slopes downward from left to right.

Б) f(x) = x^2 - 5x + 1: This is a quadratic function, which means it represents a parabolic curve on a graph. The function takes an input value x and returns an output value according to the formula f(x) = x^2 - 5x + 1.

In this formula:

• The term x^2 is the quadratic term, which determines the shape of the parabola. It means that the curve opens upward because the coefficient of x^2 is positive.
• The term -5x is the linear term, which affects the slope and position of the curve.
• The constant term 1 is the y-intercept, which is the value of the function when x = 0. So, the point (0, 1) is on the graph.

If you were to graph this function, you would get a parabolic curve that opens upward. The vertex of the parabola can be found using the vertex formula: x = -b / (2a), where a is the coefficient of x^2, and b is the coefficient of x. In this case, the vertex would be at x = 5/2, and you can plug this value into the function to find the corresponding y-coordinate.
