Question

For the function​ f, find​ (a) ​f(5​), ​(b) ​f(0​), ​(c) ​f(minus7​), ​(d) f left parenthesis one half right parenthesis
​, and​ (e) f left parenthesis negative one fifth right parenthesis
.
​f(x)equals4xplus3

literal question is f(1/2)=what

Answer 1

no

Answer 2

To evaluate the function \( f(x) = 4x + 3 \) for the various values of \( x \), we will substitute each value into the function.

(a) To find \( f(5) \):
\[
f(5) = 4(5) + 3 = 20 + 3 = 23
\]

(b) To find \( f(0) \):
\[
f(0) = 4(0) + 3 = 0 + 3 = 3
\]

(c) To find \( f(-7) \):
\[
f(-7) = 4(-7) + 3 = -28 + 3 = -25
\]

(d) To find \( f\left(\frac{1}{2}\right) \):
\[
f\left(\frac{1}{2}\right) = 4\left(\frac{1}{2}\right) + 3 = 2 + 3 = 5
\]

(e) To find \( f\left(-\frac{1}{5}\right) \):
\[
f\left(-\frac{1}{5}\right) = 4\left(-\frac{1}{5}\right) + 3 = -\frac{4}{5} + 3 = -\frac{4}{5} + \frac{15}{5} = \frac{11}{5}
\]

In summary:
- \( f(5) = 23 \)
- \( f(0) = 3 \)
- \( f(-7) = -25 \)
- \( f\left(\frac{1}{2}\right) = 5 \)
- \( f\left(-\frac{1}{5}\right) = \frac{11}{5} \)

Answer 3

I apologize if my response didn't meet your expectations. Let’s go through the evaluations of the function \( f(x) = 4x + 3 \) step-by-step once more.

(a) **Finding \( f(5) \):**
\[
f(5) = 4(5) + 3 = 20 + 3 = 23
\]

(b) **Finding \( f(0) \):**
\[
f(0) = 4(0) + 3 = 0 + 3 = 3
\]

(c) **Finding \( f(-7) \):**
\[
f(-7) = 4(-7) + 3 = -28 + 3 = -25
\]

(d) **Finding \( f\left(\frac{1}{2}\right) \):**
\[
f\left(\frac{1}{2}\right) = 4\left(\frac{1}{2}\right) + 3 = 2 + 3 = 5
\]

(e) **Finding \( f\left(-\frac{1}{5}\right) \):**
\[
f\left(-\frac{1}{5}\right) = 4\left(-\frac{1}{5}\right) + 3 = -\frac{4}{5} + 3 = -\frac{4}{5} + \frac{15}{5} = \frac{11}{5}
\]

### Final results:
- \( f(5) = 23 \)
- \( f(0) = 3 \)
- \( f(-7) = -25 \)
- \( f\left(\frac{1}{2}\right) = 5 \)
- \( f\left(-\frac{1}{5}\right) = \frac{11}{5} \)
