F(x)=(x-2)(x+4) what is the y-intercept and x-intercept
GarryVolchara [31]

Answer:

x-int=-8, y-int=2,-4

Step-by-step explanation:

for the x-int

you set x to 0 then solve the equation to get -8

for the y-int

you set y(or in this case f(x)) to 0 then solve. You solve this by spilting this into 2 linear equations; x-2=0 and x+4=0, then you solve them both to get the two y-intercepts, 2 and -4

What are the solutions of this equation 16-2x^2=-64
xenn [34]

Answer:

x = ± 2\sqrt{10}

Step-by-step explanation:

Given

16 - 2x² = - 64 ( subtract 16 from both sides )

- 2x² = - 80 ( divide both sides by - 2 )

x² = 40 ( take the square root of both sides )

x = ± \sqrt{40} = ± \sqrt{4(10)} = ± 2\sqrt{10}
