Lemur [1.5K]

Answer:

\huge\boxed{\sf x = \pm \sqrt{7} }

Step-by-step explanation:

<u>Given function:</u>

f(x)=x^2-7

<u>We can also write it as:</u>

y =x^2-7

x-intercept is the point where y = 0

Put y = 0 in the above equation

0=x^2-7\\\\Add \ 7 \ to \ both\ sides\\\\7 = x^2\\\\Take \ sqrt \ on \ both \ sides\\\\\pm \sqrt{7} =x\\\\x = \pm \sqrt{7} \\\\\rule[225]{225}{2}

1. Describe the transformations necessary to transform the graph of
lana66690 [7]

Answer:  

- The function f(x) must be shifted right 1 unit.

- The function f(x)  must be shifted up 4 units.

- The function f(x)  must be stretched vertically by a factor of 3.

Step-by-step explanation:

There are some transformations for a function f(x):

If f(x)+k, then the function is shifted up "k" units.

If f(x)-k, then the function is shifted down "k" units.

If f(x+k), then the function is shifted left "k" units.

If f(x-k), then the function is shifted right "k" units.

If bf(x) and b>1, then the function is stretched vertically by a factor of "b".

If bf(x) and 0, then the function is compressed vertically by a factor of "b".

In this case we have the following parent function f(x) :

f(x)=x^2

And the function g(x):

g(x) = 3(x - 1)^2 + 4

Based on the explained before, we can describe  the transformations necessary to transform the graph of f(x)  to the graph of g(x) :

- The function f(x) must be shifted right 1 unit.

- The function f(x)  must be shifted up 4 units.

- The function f(x)  must be stretched vertically by a factor of 3.

The height of a triangle is 7 cm longer than its base. The area of the triangle is 60 cm². What is the base of the triangle? Ent
Whitepunk [10]

Answer:

MRCORRECT has answered the question

Step-by-step explanation:

Base = b

height =h = b+7

Area = 1/2 * b* h

60 = 1/2*b*(b+7)

120 =b2+7b

 

b2+7b-120=0

 

(b+15)(b-8) =0

b=-15 and b=8

base cannot be negative

 

so base =b =8 cm
