Solve the following quadratic function

Leya [2.2K]

Answer:

x = ± 10

Step-by-step explanation:

to solve the equation let y = 0 , that is

100 - x² = 0 ( add x² to both sides )

100 = x² ( take square root of both sides )

± $\sqrt{100}$ = x , that is

x = ± 10

Will give brainliest!!

vivado [14]

Answer:

continuous.

Step-by-step explanation:

Given function is $f(x)=5x^4-9x^3+x-7$ .

and value of a = 7.

Now we need to find if the given function $f(x)=5x^4-9x^3+x-7$ is continuous or not.

By definition of continuity, we know that a function is continuous at a given point if both left and right hand limits are equal.

Left Hand Limit = LHL

$LHL=\lim_{x\rightarrow 7^-}f(x)=5(7)^4-9(7)^3+(7)-7=8918$

Right Hand Limit = RHL

$RHL=\lim_{x\rightarrow 7^+}f(x)=5(7)^4-9(7)^3+(7)-7=8918$

Since both limits are equal at a=7 so we can say that given function is continuous at a=7
