Expert Solution
Step 1

NOTE: Refresh your page if you can't see any equations.

.

f\left(x\right)=\frac{4x^2-x+2}{\sqrt{x}}

take x=1/4

f\left(\frac{1}{4}\right)=\frac{4\left(\frac{1}{4}\right)^2-\frac{1}{4}+2}{\sqrt{\frac{1}{4}}}

f\left(\frac{1}{4}\right)= \frac{4\cdot \frac{1}{16}-\frac{1}{4}+2}{\frac{1}{2}}

f\left(\frac{1}{4}\right)= \frac{\frac{1}{4}-\frac{1}{4}+2}{\frac{1}{2}}

f\left(\frac{1}{4}\right)= \frac{2}{\frac{1}{2}}

f\left(\frac{1}{4}\right)= 2\cdot 2

f\left(\frac{1}{4}\right)= 4
