Find f(-5)<br><br> f(x) = -4x + 3

Marina CMI [18]

For this case we have a function of the form $y = f (x)$

Where:

$f (x) = - 4x + 3$

We must find the value of the function when the variable x is -5.

Then, substituting, $x = -5$

$f (-5) = - 4 (-5) +3$

We have that by sign law $- * - = +$

$f (-5) = 20 + 3\\f (-5) = 23$

Answer:

$f (-5) = 23$

Jen knows that (-1, 41) and (5, 41) lie on a parabola defined by the equation y=4x^2-16x+21. How can I find the coordinates of t

andreyandreev [35.5K]

The vertex is at (2, 5).

To find the vertex, we first find the axis of symmetry; this is given by

x = -b/2a

For our equation, b = -16 and a = 4:
x = -(-16)/2(4) = 16/8 = 2

We substitute this back into our equation:
y = 4(2)² - 16(2) + 21 = 4(4) - 32 + 21 = 5

Therefore the vertex is at (2, 5).
