LenKa [72]

Answer:

f(x) = 4x² - 1

Step-by-step explanation:

The given function is; f(x) = x²

Now, when stretched vertically by a factor of 4, we have;

f(x) = 4x²

It's now shifted 1 unit down.. Thus, the final function will be;

f(x) = 4x² - 1

The y-intercept of the graph of a line is (-2). The line also passes through the point (5, 1).

MAVERICK [17]

Answer:

y = 3/5 x - 2

Step-by-step explanation:

To find the equation of the line, calculate the slope using two points. With the slope and one point, substitute them into the point slope form and simplify as needed.

Use the points (5,1) and (0, -2) since -2 is the y-intercept.

Slope = $\frac{y_2-y_1}{x_2-x_1}=\frac{1--2}{5-0}=\frac{3}{5}$

y - -2 = 3/5 (x - 0)

y + 2 = 3/5(x)

y = 3/5 x - 2
