Find the zeros of the function. Write the smaller solution first, and the larger solution second. g(x)=-10x^2 +490

olya-2409 [2.1K]

Answer:

x1= -7

x2=7

Step-by-step explanation:

To find the zeros of a polynomial function, you need to factorize it into multiple monomials or simply use a formula. Most questions want you to factorize the function, so I will solve this by factorization

g(x)=-10x^2 +490

0= -10x^2 +490 ----> we looking for zeroes, so g(x)=0

-10(x^2 - 49)=0 ---> divide -10 from both number

x^2 - 49 =0 ---> divide both side by -10, notice that 49 is 7^2

(x+7)(x-7)=0 ---> x^2 - y^2 = (x+y) (x-y)

x+7 = 0

x= -7

x-7=0

x= 7

Algebra question help needed please

Bess [88]

F(x)= 0.02x^2 + 0.08x + 30.6

so for f(0) all that means is where you see x plug 0 for x..

f(0)= 0.02(0)^2+ 0.08(0) + 30.6
f(0)= 30.6

f(4)= 0.02(4)^2 + 0.08(4) + 30.6

f(10)= 0.02(10)^2 + 0.08(10) + 30.6

attached are calculated answers
