When you insert 0.75 in the function, the answer will be -0.8125

Explanation:

You will solve it easily by putting 0.75=3/4 into function equation.

Now you will have -1+(3/16)= -13/16 = -0.8125

I would prefer to retain fractions as the expression is given in fractions.

Explanation:

Given
f(x)=−1+14x
To find f(34), insert value of x in both sides of the equation. We obtain
f(34)=−1+14×34
⇒f(34)=−1+316
Simplifying RHS we obtain
f(34)=−16+316
f(34)=−1316
