Answer:

B-26

Step-by-step explanation:

f(x)=-2(5-x)-10 f(-3)

f(-3)=-2(5-(-3))-10

f(-3)=-2(5+3)-10

f(-3)=-2(8)-10

f(-3)=-16-10

f(-3)=-26

Answer:

$f(x)=(2x+1)(2x-1)$ .

Step-by-step explanation:

We want to convert the function into the form that let's us easily find the x-intercept, and it would be for the form $(ax+b)(cx+d)$ because then we can find the x-intercept in the following manner:

$(ax+b)(cx+d)=0$

$x=-b/a$

$x=-d/c$

We factor our function $f(x)=4x^2-1$ and get

$\boxed{f(x)=(2x+1)(2x-1)}$

Now this form let's us easily find the x-intercepts:

$x=-1/2$

$x=1/2$

and so we pick the second choice: f(x)=(2x+1)(2x-1).
