Question

If f(x) = 4x-x², find square root f(3/2)

Answer 1

Answer:

$\frac{\sqrt{15} }{2}$

Step-by-step explanation:

$\sqrt{f(\frac{3}{2} )$ , substitute $\frac{3}{2}$ to x

$f(\frac{3}{2} )=4(\frac{3}{2} )-(\frac{3}{2} )^2$ = $\frac{15}{4}$ or 3.75

$\sqrt{f(\frac{3}{2} )$=$\sqrt{3.75}$ = $\frac{\sqrt{15} }{2}$
