Which equation, when graphed, has x-intercepts at (-1,0) and (-5,0) and a y-intercept at (0, -30)?

Vladimir [108]

If a function has roots -1 and -5, it must be in the form

$f(x)=a(x+1)(x+5)$

We can fix the coefficient a by imposing the passing through (0,-30):

$f(0)=-30=a(1)(5)\iff a=-6$

So, the function is

$f(x)=-6(x+1)(x+5)$

What is f(5) if f(1) = 3.2 and f(x + 1) = (f(x))?

scoray [572]

Answer:

The value of f(5) is 3.2.

Step-by-step explanation:

It is given that f(1) = 3.2 and

$f(x+1)=f(x)$

Substitute x=1 in the above equation.

$f(1+1)=f(1)$

$f(2)=3.2$

Substitute x=2 in the given equation.

$f(2+1)=f(2)$

$f(3)=3.2$

Substitute x=3 in the given equation.

$f(3+1)=f(3)$

$f(4)=3.2$

Substitute x=4 in the given equation.

$f(4+1)=f(4)$

$f(5)=3.2$

Therefore the value of f(5) is 3.2.
