Sanjay graphs a quadratic function that has x-intercepts of –3 and 7. Which functions could he have graphed?
kykrilka [37]

we will select each options and find zeros

(a)

g(x)=x^2-4x-21

for finding x-intercept , we can set g(x)=0

and then we can solve for x

g(x)=x^2-4x-21=0

now, we can factor it

(x-7)(x+3)=0

we get

x=7,x=-3

so, this is TRUE

(b)

g(x)=(x-3)(x+7)

we can set it to 0

and then we can solve for x

g(x)=(x-3)(x+7)=0

we get

x=3,x=-7

so, this is FALSE

(c)

g(x)=3x^2-12x-63

we can set it to 0

and then we can solve for x

g(x)=3x^2-12x-63 =0

3(x^2-4x-21) =0

3(x-7)(x+3) =0

x=-3,x=7

so, this is TRUE

(d)

g(x)=-(x+3)(x-7)

now, we can set it to 0

and then we can solve for x

g(x)=-(x+3)(x-7)=0

x=-3,x=7

so, this is TRUE

(e)

we have

g(x)=x^2+4x-21

now, we can set it to 0

and then we can solve for x

g(x)=x^2+4x-21=0

(x+7)(x-3)=0

x=-7,x=3

so, this is FALSE
