Given the equation y=14x2−5, the minimum is ___ and the range is ___
mel-nik [20]

Answer:

The minimum is -5

The range is y \ge -5

f(14) = 2739

Step-by-step explanation:

Given

y = 14x^2 - 5

Solving (a): The minimum

A quadratic function is represented as:

y = ax^2 + bx + c

If a > 0, then the function has a minimum

By comparison

a = 14 --- the function has a minimum

b = 0

c = -5

To calculate the minimum, we first calculate the following is calculated as:

m = -\frac{b}{2a}

So, we have:

m = -\frac{0}{2*14}

m = 0

So, the minimum is at f(m)

We have: y = 14x^2 - 5

f(0) = 14 *0^2 - 5

f(0) = - 5

Solving (b): The range

In (a), we have:

f(0) = - 5 --- the minimum

This implies that the smallest value of y on the graph is -5.

So, the range is:

r = \{y|y\ge -5\}

Solving (c): f(14)

We have:

y = 14x^2 - 5

So:

f(14) = 14 * 14^2 - 5

f(14) = 2739

4 + 2p = 12<br><br> so p = what
erma4kov [3.2K]

Answer:

p=4

Step-by-step explanation:

4+2p=12

Step 1: Simplify both sides of the equation.

2p+4=12

Step 2: Subtract 4 from both sides.

2p+4−4=12−4

2p=8

Step 3: Divide both sides by 2.

2p/2=8/2

p=4

Answer:

p=4
