\frac{x^2}{36} +\frac{y^2}{100} =1

General equation is

\frac{(x-h)^2}{b^2} +\frac{(y-k)^2}{a^2} =1

Where (h,k) is the center

From the given equation h=0  and k=0

So center is (0,0)

compare the given equation with general equation

b^2 = 36  so b= 6

a^2 = 100 so a = 10

c=\sqrt{a^2 -b^2}

c=\sqrt{100 -36}= 8

Vertices are (h, k+a) and (h, k-a)

We know h=0  , k=0  and a= 10

Vertices are (0,-10)  and (0,10)

Foci are (h, k+c)  and (h,k-c)

We know h=0  , k=0  and c=8

Foci are (0,-8)  and (0,8)

Given the function f(x) = -5|x + 1| + 3, for what values of x is f(x) = -12? O X= -2. x = 1 O x= -2 x = 4 O x = 2. x = 4 O x = 2
puteri [66]

The values are x= -2 and x =4 of the given function f (x) =-5|x+1| +3

<h3>What is function?</h3>

Function is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

According to the question,

The given function is

f(x) = -5|x + 1| + 3

Here f(x) = -12

Substitute f(x) and solve for x

- 12 = -5|x + 1| + 3

By subtracting 3 on both sides

- 12 - 3 = -5|x + 1| + 3 - 3

- 15 = -5|x + 1|

By dividing -5 on both sides

3 = |x + 1|

We get absolute values for the function.

x + 1 = 3 , x + 1 = -3

By subtracting 1 on both sides

x + 1 - 1 = 3 - 1 = 2\\\\x + 1 - 1 = - 3 - 1 = -4\\\\x = 2 ,  x = - 4

Therefore, the values of x are 2 and - 4 of the given function f (x) =-5|x+1| +3
