Answer:

The standard form as y=5x^2+30x+41

Step-by-step explanation:

Given: A function which is written in vertex form or intercept form.

We have to re-write it  in standard form that in terms of

Given y = 5(x+3)^2-4

Squaring  using (a+b)^2=a^2+b^2+2ab , we get,  

y=5(x^2+9+6x)-4

Multiply 5 inside , we get,

y=5x^2+45+30x-4

Solving further , we get,

y=5x^2+30x+41

Thus , we have obtained the standard form as y=5x^2+30x+41

Answer: The standard form of equation will be

f(x)=5x^2+30x+41

Step-by-step explanation:

Since we have given that

The vertex form of equation is given by

y=5(x+3)^2-4

We need to find the standard form :

Standard form is written as :

f(x)=ax^2+bx+c

So, our equation becomes,

y =5(x+3)^2-4\\\\y=5(x^2+9+6x)-4\\\\y=5x^2+45+30x-4\\\\y=5x^2+30x+41

Hence, the standard form of equation will be

f(x)=5x^2+30x+41

The earth orbits the sun, similar to how the moon orbits the earth. Is the earth the only planet to orbit the sun?
