Given f(x)= 3x+(1/4), Find f(1) and f(-1)

Pachacha [2.7K]

Answer:

$f(1)=\frac{13}{4}$

$f(-1) = -\frac{11}{4}$

Step-by-step explanation:

Given f(x) = 3x + (1/4), Find f(1) and f(-1)

$f(x) = 3x + (1/4)$

$f(1) = 3(1) + (1/4)$

$f(1) = 3 + (1/4)$

$f(1)=3\frac{1}{4}$

$f(1)=\frac{13}{4}$

$f(x) = 3x + (1/4)$

$f(-1) = 3(-1) + (1/4)$

$f(-1) = -3 + (1/4)$

$f(-1) = -\frac{12}{4} +\frac{1}{4}$

$f(-1) = -\frac{11}{4}$

Hope this helps!

Given that a line has a slope of -3 and a point on the line is (2,-4),

almond37 [142]

The equation in Point Slope Form is

y + 4 = -3(x - 2)

We can convert this to Slope-Intercept Form by isolating y.

y + 4 = -3(x - 2)
y + 4 = -3x + 6
Subbtract 4 from both sides.
y = -3x + 2

The equation in Slope-Intercept Form is y = -3x + 2.
